Abstract

Recent work on late stages of evolution has raised the possibility that the stars in the mass range from 4–8Mbd may ignite carbon violently off-center. Hydrodynamic evolution has been carried out for models with various central densities and for temperature profiles both with and without an inversion. It has been found that, provided ignition leads to a detonation, both types of presupernova models have essentially the same final post detonation behavior. In particular, an off-center detonation is unable to prevent a complete disruption of the star if ignition occurs at low density.
