After the hydrogen in the core of a star is used up the star moves off the main-sequence, and as the core becomes denser and hotter other fusions could happen. When the core mass density is on the order of 106 kg m−3, at what temperature would electron degeneracy pressure become important in the core? For the electron degeneracy pressure to be more important, should the temperature increase or decrease?
