SUBCLASSES OF TYPE IA SUPERNOVAE AS THE ORIGIN OF [alpha/FE] RATIOS IN DWARF SPHEROIDAL GALAXIES
Recent extensive observations of Type Ia Supernovae (SNe Ia) have revealed the existence of a diversity of SNe Ia, including SNe Iax. We introduce two possible channels in the single degenerate scenario: (1) double detonations in sub-Chandrasekhar (Ch) mass CO white dwarfs (WDs), where a thin He envelope is developed with relatively low accretion rates after He novae even at low metallicities, and (2) carbon deflagrations in Ch-mass, possibly hybrid C+O+Ne WDs, where WD winds occur at [Fe/H] at...[Show more]
