The effect of helium accretion efficiency on rates of Type Ia supernovae: double detonations in accreting binaries

Ruiter, Ashley; Belczynski, K; Sim, Stuart; Seitenzahl, Ivo; Kwiakowski, D.


The double-detonation explosion scenario of Type Ia supernovae (SNe Ia) has gained increased support from the SN Ia community as a viable progenitor model, making it a promising candidate alongside the well-known single degenerate and double degenerate scenarios. We present delay times of double-detonation SNe, in which a sub-Chandrasekhar mass carbon–oxygen white dwarf (WD) accretes non-dynamically from a helium-rich companion. One of the main uncertainties in quantifying SN rates from double...[Show more]
