Real Life Information
Vega, also known as Alpha Lyrae, is indeed a real star system that exists in our universe. It is one of the most luminous stars in the Sun's neighborhood and the fifth brightest star in the night sky. Vega is located in the northern constellation of Lyra and is a relatively close neighbor to our own solar system, at a distance of about 25 light-years.
Overview
Vega is a spectral type A0Va main-sequence star, which means it is in the prime of its life, in terms of stellar evolution. It has a mass of about 2.1 times that of the Sun and a radius 2.3 times solar. Vega's surface temperature is estimated to be around 9,600 Kelvin, much hotter than the Sun, which has a surface temperature of about 5,500 Kelvin. This high temperature gives Vega its brilliant blue-white color.
Discovery and Name
The name "Vega" comes from a loose transliteration of the Arabic word waqi', which means "falling" or "landing", via the phrase "the falling eagle". Vega was one of the first stars whose distance was estimated, via parallax measurements, by Friedrich Wilhelm Bessel in 1838. It was also one of the first stars to have its spectrum photographed, by Henry Draper in 1872.
Rotation and Magnetic Field
Vega rotates rapidly, with a velocity at its equator of about 236 kilometers per second. This rapid rotation causes the star to be oblate, with its equatorial diameter being about 23% larger than its polar diameter. Vega also has a relatively strong magnetic field for a star of its type, which is thought to be generated by its rapid rotation.
Planetary System
In 2006, an excess of infrared radiation was detected around Vega, similar to that produced by a disk of dust. This led to speculation that Vega may have a planetary system, with the dust being produced by collisions between planetesimals. However, no planets have been directly observed around Vega as of yet.
Cultural Significance
Vega has been a fixture in human culture since ancient times, due to its brightness and the fact that it is visible from most of the Earth. It was used as the North Star around 12,000 BC and will be so again around the year 14,000 due to the precession of the equinoxes. Vega is also one of the stars that make up the Summer Triangle, along with Deneb and Altair.
