[Mesa-users] How mesa burning produced?

[Rob Farmer]

Mesa will burn he4 when ever it reaches the temperature/density/composition
sufficient to burn he4.

I suggest you try to follow the material here
https://billwolf.space/projects/leiden_2019/ to see what you need to do to
follow bursts on a neutron star.
