Star Evolution

How does a low-mass star evolve?

A low-mass star is sometimes called a red dwarf. It is born fusing hydrogen into helium; it continues to do so until it stops, never really changing size and form during that time. It ends its life cycle as a white dwarf. A typical low-mass star, containing one-tenth the mass of the Sun, has a luminosity about one-thousandth that of the Sun, and a main sequence lifetime of about one trillion years.
