After Leaving the Main Sequence, Vega Will Become a Class-M Red Giant and Shed Much of Its Mass, Finally Becoming a White Dwarf. What Kind of Star Is Vega?...
After leaving the main sequence, Vega will become a class-M red giant and shed much of its mass, finally becoming a white dwarf.
What kind of star is Vega?
Vega, also called Alpha Lyrae, brightest star in the northern constellation Lyra and fifth brightest in the night sky, with a visual magnitude of 0.03. It is also one of the Sun's closer neighbours, at a distance of about 25 light-years. Vega's spectral type is A (white) and its luminosity class V (main sequence).
Vega belongs to the spectral class A0 V, which means that it is a bluish white main sequence star that is still fusing hydrogen to helium in its core. The star will eventually evolve into a red giant and later become a white dwarf.
