Yellow dwarfs are small, main sequence stars.
The Sun is a yellow dwarf. A red dwarf is a small, cool, very

brightest star in the sky is Sirius, also known as the “Dog
Star” or, more officially, Alpha Canis Majoris, for its position in the constellation Canis Major. Sirius is a binary
star dominated by a luminous main sequence
star, Sirius A, with an apparent magnitude of -1.46.
The most massive stars can burn out and explode in a supernova after only a
few million years of fusion. A star with a mass like the Sun, on the other hand, can continue fusing hydrogen for
about 10 billion years.
