The double detonation of a double degenerate system, from Type Ia supernova explosion to its supernova remnant
Type Ia supernovae (SNe) are believed to be caused by the thermonuclear
explosion of a white dwarf (WD), but the nature of the progenitor system(s) is
still unclear. Recent theoretical and observational developments have led to
renewed interest in double degenerate models, in particular the "helium-ignited
violent merger" or "dynamically-driven double-degenerate double-detonation"
(D$^6$). In this paper we take the…
