altair star temperature

For example, some of the physical characteristics of the star Altair include: Mass: 1.7 M ☉ She maketh the heart of me! The star is high in the southeast at nightfall, at one corner of the bright Summer Triangle. RA = 20h 41m 25.9s, Dec = +45° 16' 49". The angular diameters of 15 stars, R. Hanbury Brown, J. Davis, L. R. Allen, and J. M. Rome, "Altair: definition of Altair in Oxford dictionary (American English)", NAME ALTAIR -- Variable Star of delta Sct type, "Altair's Oblateness and Rotation Velocity from Long-Baseline Interferometry", "Bulletin of the IAU Working Group on Star Names, No. Spatially resolving the surfaces of nearby stars promises to advance our knowledge of stellar physics. The relationship between B-V and temperature is illustrated in Figure 2. His articles have appeared in numerous publications including Space.com, Sky & Telescope, Astronomy and Rolling Stone. It is a rapidly moving star with an apparent motion of about one degree against the background sky in about 5000 years. [30] Medieval astrolabes of England and Western Europe depicted Altair and Vega as birds. Altair is also known as Alpha Aquilae, and it is the brightest star in the constellation Aquila the Eagle. [30], This star is one of the asterisms used by Bugis sailors for navigation, called bintoéng timoro, meaning "eastern star" [39]. Once on board, it will be released within 30 to 60 days. Altair is only 16.8 light-years from Earth, making it one of our closest stellar neighbors. (In general, dress as if it were 20 degrees F or 10 degrees C colder than the forecast.) Altair is a type-A main sequence star with approximately 1.8 times the mass of the Sun and 11 times its luminosity. Once visualized, Aquila the Eagle can be seen flying eastward through the Milky Way, apparently about to devour the tiny constellation Delphinus, the Dolphin. These characteristics include things like color, composition, size, temperature, density, shape, and mass. Vega is at the top of the triangle, with Deneb below it and to the left and Altair below both stars and to the right. [22], Along with β Aquilae and γ Aquilae, Altair forms the well-known line of stars sometimes referred to as the Family of Aquila or Shaft of Aquila. The star has a visual magnitude of 0.77. α Aquilae, α Aql) je najsjajnija zvezda sazvežđa Orao i dvanaesta najsjajnija zvezda noćnog neba. Description (Specifications) [] Altair has a rapid rotation rate, causing its spherical shape to be distorted into an oblate spheroid with an equatorial diameter 25% greater than its polar diameter, and a dimmer luminosity at the equator as compared to the poles due to the difference in gravity and temperature.. To me this was odd because normally 183 sensor cameras sell for a few hundred more than that and there didnt seem to be anything wrong. Altair is the southern apex of the Summer Triangle, which is also composed of the stars Vega and Deneb. [19], In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN)[20] to catalog and standardize proper names for stars. You can recognize Altair because it has 2 fainter stars on either side of it. Activity: As an example, we will study the star Altair to better understand the process of determining a stars temperature and luminosity. Altair Weather Forecasts. It has a mass of 1.79 solar masses and a diameter 1.8 times the Sun. Altair (Alpha Aquilae) is the brightest star in the constellation Aquila, the twelfth brightest star in the sky, and the southern point of the Summer Triangle.Its Arabic name comes from a phrase meaning "the flying eagle." The variations are a result of their temperature. Altair, also designated as α Aquilae (alpha Aquilae), is a multiple main-sequence star in the constellation of Aquila. On the first of June, Altair rises about 90 minutes after sunset, as viewed from mid-northern latitudes. [9], The term Al Nesr Al Tair appeared in Al Achsasi al Mouakket's catalogue, which was translated into Latin as Vultur Volans. The "Summer Triangle" consists of the bright stars Vega, Deneb, and Altair. The sun also is an oblate spheroid, although its flattening is difficult to measure due to the low rotation rate. Altair Airlines was a regional airline that operated out of Philadelphia from 1966 to 1982. [7][25] Also, A. Domiciano de Souza et al. By the way, if Altair were substituted for our sun, at the distance the sun is now, life on Earth would be doomed, as Altair shines with 11 times the sun’s visible light. Its rapid rotation forces Altair to be oblate; its equatorial diameter is over 20 percent greater than its polar diameter. Please donate to help us keep going, and help feed a kid! The name Altair is derived from the Arabic for "The Flying Eagle." [18], Theory predicts that, owing to Altair's rapid rotation, its surface gravity and effective temperature should be lower at the equator, making the equator less luminous than the poles. Altair VI was the inhabited sixth planet of the Altair system.The system was located in Sector 9. [4][15][16] It is 16.7 light-years (5.13 parsecs) from the Sun and is one of the closest stars visible to the naked eye. Its light curve can be approximated by adding together a number of sine waves, with periods that range between 0.8 and 1.5 hours. The bright star Altair is part of the famous Summer Triangle asterism, consisting of 3 bright stars (Vega, Deneb and Altair) in 3 different constellations. It’s a phase that can last anywhere from a few million years to a trillion years or longer.In astronomical jargon, that phase of life is known as the main sequence. Altair (ster), een ster in het sterrenbeeld Arend Altair (gemeente), een gemeente in de Braziliaanse deelstaat São Paulo Altair (maanlander), een maanlander Altair 8800, een microcomputer; Altair Engineering, een Amerikaans softwarebedrijf; Altaïr Ibn-La'Ahad, een fictief figuur uit de Assassin's Creed videogames In 2285, Leonard McCoy, who was under the influence of Spock's katra, ordered a glass of Altair water at a bar he frequented on Earth. At 1200 rpm, the nominal torque is around 300 Nm. Although the Sun's surface is only 5800 °C, for example, its core achieves a temperature of 15 million Celsius. Altair is a white A star that, at a distance of under 17 … Others include α Cen, Altair, Sirius, Achernar and Barnard's Star. For one thing, Altair needs only 10 hours to spin once on its axis, in contrast to roughly a month for our sun. Along with the stars Vega in Lyra constellation and Deneb in Cygnus, Altair forms the Summer Triangle, a prominent asterism in the northern hemisphere. The warm colour temperature means it works well in wet/reflective conditions where whiter lights can glare too much. Altair is 10.6 times brighter than the Sun. Physical Properties of Altair Altair Colour and Temperature . Altair Altair is a class A main sequence dwarf star, fusing hydrogen into helium in its core, with a temperature of about 7550 degrees Kelvin, It is about 16.8 light years away, and some 10.6 times brighter than the Sun. Altair is just 16.7 light-years from Earth, making it one of the closest naked-eye stars visible in the sky. This system was in the general vicinity of Antares, Omicron Ceti and Janus VI. However, with a surface temperature of about 7,550 K degrees (13,130 Fahrenheit or 7,277 Celsius), Altair isn’t much hotter than the sun at 5,800 K (9,980 F or 5,527 C). The cold stars appear red, and hot ones are blue. Altair has a spectral type of A7 so it has the color of white. And a prime example of a star that’s on the main sequence is Altair, the leading light of Aquila, the eagle. Stars in group B are mostly 6,000 K or cooler yet more luminous than main sequence stars of the same temperature. In other words, this mighty star spins on its axis more rapidly than Earth! Temperature can be determined by studying a stars spectrum and luminosity can be calculated from knowledge of a stars distance and apparent brightness. Stars of this spectral type have a surface temperature of about 8000 to 9000 degrees Centigrade, a diameter about twice that of the Sun and a luminosity about 11 or 12 Suns. And sweet as the heavenly weather In Asia, this hazy band across our sky is known as the Celestial River. Luminosity is a measure of the energy radiated by an object, for example a star or a galaxy. Altair is a white A star that, at a distance of under 17 … And a prime example of a star that’s on the main sequence is Altair, the leading light of Aquila, the eagle. One of the tankers attacked and damaged in the June 2019 Gulf of Oman incident was named Front Altair. Altair has a surface temperature of 7,500 K and a luminosity equal to 10.6 times the luminosity of the Sun. When a gaseous orb, like a star, spins fast enough, it tends to expand at the middle, like a beach ball that is squeezed at the top and bottom. [18] Other interferometric studies with multiple telescopes, operating in the infrared, have imaged and confirmed this phenomenon. A class A (A7) hydrogen-fusing dwarf with a temperature of 7550 degrees Kelvin, Altair is the coolest of the three (with Vega and Deneb warmer at … "[42], The bright primary star has the multiple star designation WDS 19508+0852A and has several faint visual companion stars, WDS 19508+0852B, C, D, E, F, and G.[11] All are much more distant than Altair and not physically associated. Read more about the Summer Triangle. Higher temperatures usually reveal greater mass, at least for main sequence stars, and Altair is thought to be in excess of 1.7 times the mass of our sun. Weather Underground provides local & long-range weather forecasts, weatherreports, maps & tropical weather conditions for the Altair area. Many depictions place Altair as the head or neck of an eagle with outstretched wings. In Japan, Altair is Hikoboshi, and Vega is Orihime (or Tanabata). While temperature variations won't determine if you can observe, the forecast can be handy choosing clothing for cold observing conditions. Altair kan verwijzen naar: . The WGSN's first bulletin of July 2016[21] included a table of the first two batches of names approved by the WGSN, which included Altair for this star. [34] However, Altair is better known by its other names: Qiān Niú Xīng (牵牛星 / 牽牛星) or Niú Láng Xīng (牛郎星), translated as the cowherd star. For other uses, see USS Altair. and our Sun, yellow, as an peak around 500nm and a surface effective temperature of 5800K. In other words, it is wider than it is tall. The main sequence is named for a relationship between a star’s brightness and its surface temperature or color. Temperature can be determined by studying a stars spectrum and luminosity can be calculated from knowledge of a stars distance and apparent brightness. An Astronomer can then use the color indices for a star, after correcting for reddening and interstellar extinction, to obtain an accurate temperature of that star. With the bright stars Deneb and Vega, Altair (Arabic for “flying eagle”) forms the prominent asterism of the Summer Triangle. If star A has a hotter surface temperature than star B, then... Star A is smaller. The magnet temperature has a great effect on the remanent flux density of magnet. On a stellar spectrum, the profile can be assimilated to a Planck’s function and the peak indicates the star temperature. Second, Altair stands out because it is a weak and unusual variable star with as many as nine different rates of brightness waxings and wanings. [31], The Koori people of Victoria also knew Altair as Bunjil, the wedge-tailed eagle, and β and γ Aquilae are his two wives the black swans. For the stars of the main sequence, luminosity is directly related to their temperature - the hotter a star is, the more luminous it is. The location of Altair VI on "The Explored Galaxy" star chart. This is why a new model of magnet depending on temperature has been introduced inside Flux software. Hot, rapidly rotating star Altair, showing surface features and the fact that Altair’s fast rotation has flattened it. The princess became so enamored of the herdsman that she neglects her weaving duties. The USS Altair was an experimental Federation starship in the late 24th century. This acts enrages the princess’s father, the Celestial Emperor, who decrees that the herdsman must stay away from his daughter, on the opposite side of the River. Spock was known to drink Altair water. Altair (alpha Aquilae) is de helderste ster in het sterrenbeeld Arend (Aquila).Altair is een van de drie sterren van de zomerdriehoek.De ster staat ook bekend als Atair.. Altair behoort tot het 40-tal sterren dat dichter dan 5 parsecs bij de zon staat en behoort met sterren als Sirius en Procyon dus tot onze naaste omgeving. Altair has a spectral type of A7 so it has the color of white. The reason is that these stars are much larger than main sequence stars. This work was published by G. T. van Belle, David R. Ciardi and their co-authors in 2001. [26], Altair is one of the few stars for which a direct image has been obtained. [28] This name was applied by the Arabs to the asterism of Altair, β Aquilae, and γ Aquilae and probably goes back to the ancient Babylonians and Sumerians, who called Altair "the eagle star". The name Altair is Arabic in origin and has the same meaning as the name of the constellation Aquila in Latin; that is, they both mean simply “eagle.”. Hot and blue stars have smaller and negative values of B-V than the cooler and redder stars. The brightness variations are too small to measure without sensitive instruments, but likely are related to the star’s high rotation rate. They are only permitted to meet once a year, when magpies form a bridge to allow them to cross the Milky Way. Rough estimates are that Altair’s flattening is about 14%. It was designed to be highly maneuverable at warp speeds, but suffered from unacceptably low power efficiency. Altair was later observed to be flattened by infrared interferometric measurements made by the Palomar Testbed Interferometer in 1999 and 2000. At least two features of the star Altair make it distinctive. The people of the Murray River knew the star as Totyerguil. The researchers, led by John Monnier of U-M, used optical interferometry to get this image. What’s more, Altair is flanked by two other stars, Tarazed and Alshain. and our Sun, yellow, as an peak around 500nm and a surface effective temperature of 5800K. First, Altair rotates rapidly. [3][4] Altair possesses an extremely rapid rate of rotation; it has a rotational period of approximately 9 hours. An Astronomer can then use the color indices for a star, after correcting for reddening and interstellar extinction, to obtain an accurate temperature of that star. His small book on world star lore, Constellations, was published by Running Press. [40] The Russian-made Beriev Be-200 Altair seaplane is also named after the star.[41]. In 2020, we are donating 8.5% to No Kids Hungry.

The image above shows the uncropped view of Altair (North is up) through the Takahashi E-180 Astrograph. Altair has a spectral type of A7V, a surface temperature of 7500° Kelvin and a luminosity 10.6 times the Sun. Altair (Alpha Aquilae) is the brightest star in the constellation Aquila, the twelfth brightest star in the sky, and the southern point of the Summer Triangle.Its Arabic name comes from a phrase meaning "the flying eagle." This phenomenon, known as gravity darkening or the von Zeipel effect, was confirmed for Altair by measurements made by the Navy Prototype Optical Interferometer in 2001, and analyzed by Ohishi et al. It was this design flaw that kept the Altair from going into full-scale production. Hi/Low, RealFeel®, precip, radar, & everything you need to be ready for the day, commute, and weekend! The Altair 8800 was one of the first microcomputers intended for home use. [33], In Chinese, the asterism consisting of Altair, β Aquilae, and γ Aquilae is known as Hé Gǔ (河鼓; lit. This activity may be due to convection cells forming at the cooler equator. realized that Altair would be rotationally flattened, they had insufficient data to experimentally observe its oblateness. SECTION 3: Identification of the color of a star Star Temperature Color Betelgeuse Polaris B Centauri Achernar Antares Spica A Aldeberan Sun Regulus Arcturus Vega Sirius Fomalhaut Altair Procyon Lacaille 8760 3.400 6,300 22,400 17,400 3,500 22,400 4,100 5,800 … Also called Alpha Aquilae, Altair is the brightest star in Aquila. Altair is only 16.8 light-years away from Earth, making it one of our nearest stellar neighbors. Od zvezda prve magnitude, od Altaira su bliže samo alfa Kentaura, Sirijus i Procion. The position of Altair is RA: 19h 50m 47.0s, dec: +08° 52′ 06″. [17], Altair rotates rapidly, with a velocity at the equator of approximately 286 km/s. Altair, or Alpha Aquilae, is the brightest star in the constellation Aquila, the Eagle. Earlier measurements of the star's spectrum, or light-wave pattern, had hinted that Altair was rotating very fast. Altair's surface temperature is about 7,700 K. Altair is the brightest star in the constellation Aquila. 4 Altair (α Aql) is a white main sequence dwarf star belonging to the constellation Aquila (The Eagle). Blue stars are very hot, red ones are very cold (few thousands kelvin still!) The apparent magnitude of Altair is 0.77. Using optical long-baseline interferometry, we constructed a near-infrared image of the rapidly rotating hot star Altair with a resolution of <1 milliarcsecond. Anyone have experience with Altair mono cooled cameras? Altair do sell two versions of the 294C though, there is the ' Pro ' version which is fan cooled and retails for £675 and the ' Pro Tec ' version which is both fan and peltier tec cooled (can cool to -45 degrees below ambient) and retails for £1025. Altair is the name of three United States navy ships: USS Altair (AD-11), USS Altair (AK-257) and USNS Altair (T-AKR-291). Image via Wikipedia. "river drum two", meaning the "second star of the drum at the river"). Most of the stars that populate the galaxy are in the prime of life. She is the fairest of three; It shines with 63 solar luminosities. Alpha Aquilae (Altair) is the brightest star in the constellation Aquila and the twelfth brightest star in the night sky.It has a temperature of about 6,900 to 8,500 kelvin. This rapid rotation tends to flatten the star a bit, much as a pizza crust flattens as it spins. On a stellar spectrum, the profile can be assimilated to a Planck’s function and the peak indicates the star temperature. "river drum"). The star's effective temperature is 7,800 Kelvin which is hotter than our own Sun's effective Temperature which is 5,777 Kelvin. Read more about the study here. When you see them, you might think of these stars as walking three abreast and arm-in-arm across the heavenly sphere. All three stars are extremely bright in a region with few other bright stars. So for £1025, what do you get in … Birth of the Federationreferr… - posted in Beginning Deep Sky Imaging: So I was looking on the classifieds the other day and I happened to see an Altair Hypercam 183M go up and sell for $575. Deneb has a spectral typeof A2Ia, a surface temperature of 8525° Kelvin and a luminosity 54,000 times the Sun. On the other hand, cooler stars emit less energy - … The star Altair has an apparent magnitude of 0.8 while the star Polaris has an apparent magnitude of 2.0. In astronomy, stellar classification is a way of grouping stars by temperature.Star temperature can be measured by looking at its spectrum, the type of light that the star shines.. Stars are also grouped into spectral types or classes by color. This forecasts temperatures near the ground. [5] It is a weak source of coronal X-ray emission, with the most active sources of emission being located near the star's equator. Owing to its rapid rotation, Altair's radius is larger at its equator than at its poles; it is also cooler at the equator than at the poles. [27] The false-color image was published in 2007. It lies at a distance of approximately 16 light years from Earth, and its color is pale yellow. [6] The polar axis is inclined by about 60° to the line of sight from the Earth. This star requires only about 10 hours to spin once on its axis, in contrast to 24 hours for our Earth to spin or roughly a month for our sun. The image above shows the uncropped view of Deneb (North is up) through the Takahashi E-180 Astrograph. By the end of the year, late-night observers will miss it altogether as it sets less than three hours after the sun. Colour – Temperature Relationship: Another method to measure the temperature of stars is by analyzing their color. It is also not difficult to view Altair with the naked eye, since it forms one of the vertices of the famous Summer Triangle asterism, with the other two points marked by the stars Deneb in Cygnus and Vega in Lyra. He's a former planetarium director in Little Rock, Fort Worth and Denver and an adjunct faculty member at Metropolitan State University of Denver. Based on the star's spectral type of G8IVvar , Alshain's colour and type is yellow subgiant star. Altair is a type-A main sequence star with approximately 1.8 times the mass of the Sun and 11 times its luminosity. It is now so entered in the IAU Catalog of Star Names. The scientific community is very interested in Altair, as it is one the locations from which radio signals were … Altair, or Alpha Aquilae, is the brightest star in the constellation Aquila, the Eagle. It is currently in the G-cloud—a nearby interstellar cloud, an accumulation of gas and dust. (2005) verified gravity darkening using the measurements made by the Palomar and Navy interferometers, together with new measurements made by the VINCI instrument at the VLTI. The mass of Altair is between 1.7 and 1.8 times the mass of our sun. A light-year is a unit commonly used in astronomy as a measure of. (TNG episode: "Yesterday's Enterprise", TNG reference: The Continuing Mission) Ruins on the surface of at least one world in this system indicated that the Preservers once inhabited this planet whilst certain locations show evidence that the Vegan Tyranny also had a connection to Altair. It is the 12th brightest star in the night sky overall and located approximately 16.73 light … Altair is separated from the similar-looking (but brighter) star Vega in the constellation Lyra by the great starlit band of the Milky Way. DStar Altair MC-E front light review. Activity: As an example, we will study the star Altair to better understand the process of determining a stars temperature and luminosity. Our Sun is one such example. Get the forecast for today, tonight & tomorrow's weather for Altair, TX. Wow! The star has a visual magnitude of 0.77. Altair is the 12th brightest star, and so it is respectably bright (apparent magnitude 0.76 or 0.77), a fact that increases your likelihood of spotting it in summer or autumn skies. Altair's surface temperature is about 7,700 K. Altair is the brightest star in the constellation Aquila. Having exhausted the hydrogen supply in its core, the star is now in the process of cooling and expanding. Although the star has been in the human consciousness since ancient Babylonian and Sumerian times, when it was known as “the eagle star”, the name Altair, meaning “the flying eagle” in Arabic, has only been in use by Western cultures since medieval times. Other Information. (FASA RPG module: The Federation) 1. Bottom line: Altair is the brightest star in the constellation Aquila, and one of the closest stars to our solar system. [nb 2][6] This is a significant fraction of the star's estimated breakup speed of 400 km/s. One story common in China, Japan and Korea is of a young herdsman (Altair) who falls in love with a celestial princess (Vega), who weaves the fabric of heaven. Though three of the stars of the Summer Triangle are all white in color and hotter than the Sun, all are also individuals. The Emperor finally listened to the princess’s pleas, however, and allowed the herdsman to cross the Celestial River once per year, on the seventh day of the seventh month. Distance. It is an A-type star 16.6 light-years from Earth.Altair rotates at the fast speed of more than 200 km (120 miles) per second. How can this be? The apparent magnitude of Altair … Based on the star's spectral type of A7IV-V , Altair's colour and type is blue - white subgiant star. [23], Altair is a type-A main sequence star with about 1.8 times the mass of the Sun and 11 times its luminosity. So we have the following in the “optical train”: Telescope > Reducer/Flattener (55mm spacing) > Filter Holder (17.0mm) > Stacked extension rings (total 20.5mm) > Camera (17.5mm flange to sensor spacing). EarthSky’s yearly crowd-funding campaign is in progress. Astronomers define star brightness in terms of apparent magnitude — how bright the star appears from Earth — and absolute magnitude — how bright the star appears at … If it rains on the day of the festival of Tanabata, it is said to be Orihime’s tears because Hikoboshi could not navigate the treacherous waters of the Celestial River. By the end of September it approaches the meridian as night falls. NASA announced Altair as the name of the Lunar Surface Access Module (LSAM) on December 13, 2007. It lies only 16.7 light years from Earth. In general, a star's temperature determines its color, from … [6][7] Altair rotates rapidly, with a rotational period of about 9 hours;[7] for comparison, the equator of the Sun makes a complete rotation in a little more than 25 days. Altair is a very fast spinner, with a rotational velocity of about 286 km/s, or 71.5 percent of its estimated breakup speed (400 km/s). The equatorial radius of the star was estimated to be 2.03 solar radii, and the polar radius 1.63 solar radii—a 25% increase of the stellar radius from pole to equator. ALTAIR Pathfinder will be launched on an International Space Station resupply mission, currently manifest in April 2017. Altair of Aquila the Eagle, with two smaller constellations nearby. [9] A study with the Palomar Testbed Interferometer revealed that Altair is not spherical, but is flattened at the poles due to its high rate of rotation. Weather Underground provides local & long-range weather forecasts, weatherreports, maps & tropical weather conditions for the Altair area. [4] For comparison, the equator of the Sun requires just over 25 days for a complete rotation. Naziv Altair potiče od arapske reči al-nasr al-ta’ir, i znači „leteći orao“.Orlom ili orlovom zvezdom su ga nazivali još drevni Vavilonci i Sumeri. (Star Trek III: The Search for Spock) Altair water at Memory Beta, the wiki for licensed Star Trek works Although all stars appear white, they have different colors when carefully viewed. The traditional name Altair has been used since medieval times. Altair is the brightest star in the constellation Aquila.It has a spectral type of A7 and has a temperature of between 6,900 -> 8,500 oKSee related link for more information. Altair (Alpha Aquilae) is the brightest star in the constellation Aquila, and the 12th most luminous in the entire night sky. [38], In Western astrology, the star Altair was ill-omened, portending danger from reptiles. Three of them walk together- If you are viewing the above visualizations in a supported browser (see Note on Browser Compliance above), the times are both serialized and rendered in local time, so that the January 1st 00:00:00 row renders in the chart as 00:00 on January 1st. [35][36] These names are an allusion to a love story, The Cowherd and the Weaver Girl, in which Niulang (represented by Altair) and his two children (represented by β Aquilae and γ Aquilae) are separated from respectively their wife and mother Zhinu (represented by Vega) by the Milky Way. In 2007, University of Michigan astronomers combined light from four widely separated telescopes to produce the first picture (above) showing surface details on Altair. Altair is the name of a 1919 poem by Karle Wilson Baker. At least 2 features of the star make it distinctive. The star's effective temperature is 5,163 Kelvin which is cooler than our own Sun's effective Temperature which is 5,777 Kelvin Alshain Luminosity. Altair water was a beverage exported from the Altair system and served on such planets as Earth. The tips of the wings are formed by the Theta and Zeta stars of the constellation Aquila the Eagle, with the tail being Lambda. [5] As a result, it was identified in 2005 as a Delta Scuti variable star. In another myth Aquila is the eagle that torments Prometheus, and is shot with a poisoned arrow by Hercules. Altair Luminosity Try Professor Jim Kaler's Stars site for other information about Altair at the University of Illinois' Department of Astronomy. Altair / æ l ˈ t ɛər /, designated α Aquilae (Latinised to Alpha Aquilae, abbreviated Alpha Aql, α Aql), is the brightest star in the constellation of Aquila and the twelfth brightest star in the night sky.It is currently in the G-cloud—a nearby interstellar cloud, an accumulation of gas and dust. Altair /ælˈtɛər/,[12] designated α Aquilae (Latinised to Alpha Aquilae, abbreviated Alpha Aql, α Aql), is the brightest star in the constellation of Aquila and the twelfth brightest star in the night sky. [32] The Murray River was formed when Totyerguil the hunter speared Otjout, a giant Murray cod, who, when wounded, churned a channel across southern Australia before entering the sky as the constellation Delphinus.
