Unformatted text preview: Hotter He core does not become degenerate. No Helium flash Has a planetary nebula phase, remnant is a WD Life stages of a high (>8 Msun) mass star Begins like intermediate mass stars, but quicker still (H shell burning, He core burning, etc) End is very different (no planetary nebula) Fusion by the CNO cycle Intermediate and high-mass stars fuse H to He art a higher rate using carbon, nitrogen, and oxygen as catalysts. High core temperature enables H nuclei to overcome greater repulsion....
