Abstract:The recently proposed "dynamically driven double-degenerate double-detonation" (D 6 ) scenario posits that Type Ia supernovae (SNe) may occur during dynamically unstable mass transfer between two white dwarfs (WDs) in a binary. This scenario predicts that the donor WD may then survive the explosion and be released as a hypervelocity runaway, opening up the exciting possibility of identifying remnant stars from D 6 SNe and using them to study the physics of detonations that produce Type Ia SNe.
