Incomplete Carbon-Oxygen Detonation in Type Ia Supernovae

Incomplete carbon-oxygen detonation with reactions terminating after burning of C12 in the leading C12 + C12 reaction (C-detonation) may occur in the low-density outer layers of white dwarfs exploding as Type Ia supernovae (SNe Ia). Previous studies of carbon-oxygen detonation structure and stabilit...

Description
Summary:Incomplete carbon-oxygen detonation with reactions terminating after burning of C12 in the leading C12 + C12 reaction (C-detonation) may occur in the low-density outer layers of white dwarfs exploding as Type Ia supernovae (SNe Ia). Previous studies of carbon-oxygen detonation structure and stability at low densities were performed under the assumption that the velocity of a detonation wave is derived from complete burning of carbon and oxygen to iron. In fact, at densities Delta *r
