A systematic survey for hypervelocity runaways from thermonuclear supernovae
Kareem El-Badry, Klaus Werner, Ken J. Shen +16
The explosion of a white dwarf (WD) in a close binary can launch a surviving runaway star at velocities of . Such runaways provide a direct probe of…

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…
