Neutron Star Formation in Theoretical Supernovae — Low Mass Stars and White Dwarfs —

Abstract

The presupernova evolution of stars that form semi-degenerate or strongly degenerate O+Ne+Mg cores is discussed. For the 10–13 M ⊙ stars, behavior of off-center neon flashes is crucial. The 8–10 M ⊙ stars do not ignite neon and eventually collapse due to electron captures. Properties of supernova explosions and neutron stars expected from these low mass progenitors are compared with the Crab nebula. We also examine the conditions for which neutron stars form from accretion-induced collapse of white dwarfs in close binary systems.
