It possesses an extremely rapid rotation rate of 210 kilometers per second at its equator which translates into rotational period of approximately 9 hours. Altair is a type-A main sequence star fusing hydrogen into helium in its core. The history of the star: Altair. What is the mass of the star? ALTAIR (Alpha Aquilae). Altair is a main star in the constellation Aquila and makes up the constellation outline. Powered by Create your own unique website with customizable templates. The star has a visual magnitude of 0.77. The mass of Altair is between 1.7 and 1.8 times the mass of our sun. Altair Facts. Altair is a Subgiant Star type star. It lies only 16.7 light years from Earth. What galaxy is Altair found in? Altair, also known as Alpha Aquilae, is a Main Sequence or hydrogen fusing star of spectral type A7V. First magnitude (0.77) Altair, the 12th brightest star in the sky and the Alpha star of Aquila the Eagle, is also the southern anchor of the famed Summer Triangle, which it makes with Vega and Deneb.The Arabic name "Altair," reflective of the constellation itself, comes from a phrase meaning "the flying eagle." The mass of Altair is 2 times the mass of our sun. ; Based on the spectral type (A7IV-V) of the star, the star's … Along with the stars Vega in Lyra constellation and Deneb in Cygnus, Altair forms the Summer Triangle, a prominent asterism in the northern hemisphere. Altair has a spectral type of A7 so it has the color of white. Altair's surface temperature is about 7,700 K. Altair is the brightest star in the constellation Aquila. Altair is the twelfth-brightest star in the night sky and one of the closest stars to Earth, at a distance of only 16.7 light-years. Because of this fast spinning motion, Alpha Aquilae is oblate in shape, meaning its equator is about 20 percent larger in diameter than its polar regions. Altair is a A7IV-V subgiant star based on the spectral type that was recorded in the Hipparcos star catalogue. 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. For comparison, the Sun requires just over 25 days for a complete rotation at its equator. It is also a rapid rotator completing a rotation on its axis every nine hours (the Sun takes 25 days). The surface temperature of the star is Altair, or Alpha Aquilae, is the brightest star in the constellation Aquila, the Eagle. 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. What is the temperature of the star? Wit the Altair star being 1.7 times the mass of the sun the process will probably take a longer time then 10 billion years. Altair is 10.6 times brighter than the Sun. [A scanned copy can be viewed on this webpage] Alpha (α) Aquila, Altair, is a pale yellow star in the neck of the Eagle. The Star Altair Here is the star Altair. from p.59 of Star Names, Richard Hinckley Allen, 1889. Altair can be found in the Milky Way galaxy. The apparent magnitude of Altair is … ائر (an-nasr aá¹­-ṭā’ir) which means the flying eagle. Star. The Altair star has an apparent magnitude of 0.77, it has an absolute magnitude of 2.3, and has a b-v of 0.22. Classified as an A-type main-sequence star, and located 16.7 light-years from Earth, Altair is one of the few stars for which a resolved image of measurable nonzero extent has been obtained. Altair appears to be on the main sequence, where stars still burn hydrogen in their cores, but it’s almost twice the Sun’s size and mass.
