Dying low-mass stars
WebBecause the star’s mass is relatively low, it cannot push its core temperature high enough to begin another round of fusion (in the same way larger-mass stars can). The core continues to shrink until it reaches a density equal to nearly a million times the density of … 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.
