Description

The discovery of hypervelocity white dwarfs strongly supports the Dynamical-Driven Double-Degenerate Double-Detonation ($D^6$) model for type Ia supernova scenario. We have performed high-resolution SPH simulations of $D^6$ explosions in various double-degenerate systems. We have found several explosion modes. In this presentation, we will show observational features of these explosion modes.
