Thermonuclear explosion criteria for direct and indirect collisions of CO white dwarfs: a study of the impact-parameter threshold for detonation

Hila Glanz, Hagai B. Perets, Ruediger Pakmor

The physical collisions of two white dwarfs (WDs) (i.e. not slow mergers) have been shown to produce type-Ia-like supernovae (SNe) explosions. Most studies of WD collisions have fo…
