Monnier et al used more than 2,000 infrared images taken with the MIRC instrument on the CHARA array interferometer to produce a false color image that shows some detail on Altair… Earlier measurements of the star's spectrum, or light-wave pattern, had hinted that Altair was rotating very fast. Altair Star Color. 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. On average, the stars in this field are at a distance of about 25,000 light-years (which means it takes light 25,000 years to traverse the distance from them to us) and the width of the field is about 13.3 light-years. In 2006 and 2007, J.D. Blue-white stars are much hotter than the Sun, whereas red stars are cooler. With the bright stars Deneb and Vega, Altair (Arabic for “flying eagle”) forms the prominent asterism of the Summer Triangle. Based on the spectral type (A7IV-V) of the star, the star's colour is blue - white . Altair, or Alpha Aquilae, is the brightest star in the constellation Aquila, the Eagle. Altair, also known as Alpha Aquilae, is a Main Sequence or hydrogen fusing star of spectral type A7V.
