Scientific paper

Recent work on supernova rates strongly suggests that SNe Ia originate preferentially from intermediate mass (3 < M < 8 M&sun;) binary progenitors. A simple model (Pritchet et al. ApJL 683, L25) can be used to explain many of the systematics of SN Ia rates. This model predicts that about 2% of all white dwarfs in binaries explode as SNe Ia, and favours the “double degenerate” scenario for SNe Ia. This talk will focus on properties of binary stars, and how these properties may affect conclusions regarding the nature of SNe Ia.
