Type Ia supernovae are the thermonuclear explosion of a carbon-oxygen white dwarf. ... Coupling this to recent work by Richard Scalzo, we find that SNe Ia from white dwarfs below the Chandrasekhar mass consistently produce a modest amount of nickel (~0.5 solar masses) while Chandrasekhar mass white dwarfs produce a broader range (0.4-1.2 solar masses) - this may consistute evidence for two distinct explosion mechanisms. ...
