Altair

Altair is one of the few stars for which a direct image has been obtained.[15] In 2006 and 2007, J. D.

Altair is most notable for its extremely rapid rotation; by measuring the width of its spectral lines, it was determined that its equator does a complete rotation in about 6 1/2 hours (various other sources give 9 hours, or 10.4 hours).

ALTAIR (Alpha Aquilae). First magnitude (0.77) Altair, the 13th 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.

Altair surface features The first image of Altair's surface In 2007, Altair became the first star, other than a giant or supergiant star (such as Betelgeuse), to have its surface ts surface features imaged.

Altair is a white main sequence dwarf star of spectral and luminosity type A7 V-IV. According to various estimates, the star has about 1.7 times Sol's mass (RECONS), 1.8 times its equatorial diameter (JPL press release, 2001; T.

Altair (or Alpha Aquila) is a star (spectral class A7IV) about 16.8 light years from Earth (98 trillion miles). A 2280s freighter could travel nineteen periods from Altair to reach Gamma Hydra sector, Section 10.

Altair is the 11th brightest star in the sky. Take a look at the list of the Brightest Stars Vega, along with Deneb and Altair form the well-known Summer Triangle. More Altair information ...

Altair Related Category: Astronomy: Stars (ltä´r), brightest star in the constellation Aquila (Eagle); Bayer designation &agr; Aquilae; 1992 position R.A. 19h50.5m, Dec. +8°51&minut;. Its apparent magnitude is 0.

Altair is a white A7V main sequence star. The star is about 1.6 times the diameter of the sun. The spectral type implies an effective temperature of 8100 K, a luminosity about 9 times that of the sun, and a mass almost twice that of the sun.

Altair is a large, dry planet beneath a very unstable sun. The cause of the sun's frequent solar storms and violent flares is unknown, but such activity shuts down communications, sometimes for two months or more.

Altair is rotating so rapidly that it is 14% larger at the equator than it is at the pole. Courtesy NASA/JPL-Caltech What's in a Name: Arabic for "Aquila".

Altair is the brightest star in the constellation Aquila and the list of brightest stars in the night sky. It is an Stellar classification#Class A main sequence star with an apparent visual magnitude of 0.

Altair forms one corner of the so-called Summer Triangle with the stars Vega and Deneb, found in the constellations Lyra and Cygnus respectively.

Altair Knowledge Designs developed in 3240 in the Altair Mecomp project, where a sizable three dimensional cellular automaton was run on a massive computronium mainframe.

Altair is the 11th brightest star in the sky. It has a very rapid rotation, completing one turn every 6.5 hours. Tarazed is a giant star located near the Great Rift of the summer-time Milky Way. [ send green star] ...

The internal motors begain slewing the scope and the display flashed that I should "Center Altair" (a bright star in the constellation Aquila).

An ancient constellation whose bright star Altair marks one third of the asterism known as the "Summer Triangle". Aquila is the eagle that was the symbol of the ancient god Zeus.

A significant number of stars in the sky, such as Aldebaran and Altair, and astronomical terms such as alhidade, azimuth, and almucantar, are still today recognized with their Arabic names. History Pre-Islamic Arabs had no scientific astronomy.

Aquila's Bayer stars are generally third and fourth magnitude, except Altair (alpha Aql), the twelfth brightest star. Altair spins very rapidly, completing one revolution every 6.5 hours, which deforms the star.

In 2001, astronomers reported that fast-spinning Altair, a white star of spectral type A7, has an equatorial diameter 14-percent greater than its polar diameter, less extreme than Regulus.

These are Altair, Deneb, and Vega. These form a bright triangle, with the Southernmost star (farthest from the other two) being Altair, the brightest one (to the West) being Vega, and the one to the East being Deneb.

The alpha star Altair (arab.: the flying eagle) forms with alpha Cyg and alpha Lyr the so called Summer Triangle. See here how the stars form the eagle.

Also, Altair and Vega were thought to be lovers, who were bound not to meet each other but on the seventh day of the seventh month, Qi Xi (Tanabata in Japan and Chilseok in Korea), when the magpies form the bridge over the galactic river.

Cygnus, with the bright star Deneb in the swan's tail, appears high in the summer sky. The three bright stars Deneb, Vega (in the constellation of Lyra), and Altair (in the constellation of Aquila) mark the Summer Triangle.

Moving straight south (down) from Vega we find the bright star Altair (A7V) and the constellation Aquila (the Eagle). Altair is the second of three stars in the summer triangle.

This faint planetary can be found about 5° W of Altair and 2° NNW of m Aquilae (see finder chart below). A bright star-like planetary nebula NGC6803 is located almost 1° further North.

The target stars are all roughly 50-70 light-years from Earth, and lie in or near the Summer Triangle, a large region of the sky bounded by the bright stars Vega, Deneb, and Altair.
