WebThe ultimate life and death of a star depends on its initial mass. Today we will look at the life of low-mass stars, which are those with mass less than about 2 times the mass of the Sun (less than 2 solar masses). So the Sun is a low-mass star. All such stars follow the same basic pattern.

Some elements are produced in different ways, including through the explosion of huge stars and dying low-mass stars. Robert Hurt/IPAC/Caltech WebLow mass stars spend billions of years fusing hydrogen to helium in their cores via the proton-proton chain. They usually have a convection zone, and the activity of the convection zone determines if the star has activity similar to the sunspot cycle on our Sun. Some small stars have very deep convection zones.
