Direct Collision of White Dwarfs as a Possible Major Channel for Type Ia Supernovae
SuBo Dong, Associate Professor, Kavli Institute for Astronomy & Astrophysics, Peking University,

The explosion mechanism of Type Ia supernovae (SN Ia) is unknown. The continuity in the properties of SNe Ia across the luminosity function suggests a single dominant channel to explain the population. We argue that direct collisions of white dwarfs may be promising as such a major channel. I will present results of our efforts to test the collision model.
