Type la Supernovae: Mechanisms and Nucleosynthesis

Abstract

We summarize various explosion models of Type la supernovae and their nucleosynthesis features for both Chandrasekhar and sub-Chandrasekhar mass white dwarf models. These models provide different predictions of the photometric and spectroscopic variations among Type la supernovae, which are compared with observations. Some attempts to model the peculiar SNe 1991T and 1991bg are shown.
