Dying low-mass stars
WebAug 20, 2015 · 1.2M views 7 years ago Astronomy Today we are talking about the life -- and death -- of stars. Low-mass stars live a long time, fusing all their hydrogen into helium over a trillion years.... 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.

Then there's this tail of high-mass stars. So they're relatively rare, but because they're so massive, when they explode, they throw a lot of stuff out in space.” He’s now involved in two related research projects.
