On the Intrinsic Differences among Type IA Supernovae
Abstract
Recent observational evidence has confirmed the inhomogeneity of Type Ia supernovae. The intrinsic differences, that also entail systematic correlation between luminosity and photospheric velocity at maximum light on one side and rate of decline of the light curve on the other (the Pskovskii-Branch effect), are hard to explain by the standard model of deflagrating C+O white dwarfs. We discuss possible alternatives to this model and we favor off-center explosions in partially solid white dwarfs.
