Is Vega a white dwarf?

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).

Is Vega a white dwarf star?

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.

Why will Vega be a white dwarf?

As Vega is so much bigger and hotter than Sol, however, the star will exhaust its core hydrogen after only another 650 million years or so (for a total life of around a billion years) and turn into a red giant or Cepheid variable before puffing away its outer layers to reveal a remnant core as a white dwarf.

What color is Vega?

Vega is blue-white in color. It's sometimes called the Harp Star. It's about 25 light-years away. Many people recognize its constellation, Lyra, as a triangle of stars connected to a parallelogram.
