Abstract

The evolution of stars in the mass range of 8–12 M⊙ is summarized; it is significantly different from more massive stars (typically a 25 M⊙ star) because of smaller core mass and stronger electron degeneracy. Stars of 10-12 M⊙ undergo strong shell flashes of neon, oxygen, and silicon and the resultant iron core eventually collapse. Stars of 8–10 M⊙ form electron-degenerate O+Ne+Mg cores and undergo collapse induced by electron captures. The collapse of such less massive progenitors does lead to the Type II supernova explosion. Nucleosynthesis in these stars does not contribute much to the galactic nucleosynthesis, but provides useful information on the Crab Nebula’s progenitor.
