Light curves of type IA supernova models with different explosion mechanisms.

The deflagration, detonation, delayed detonation, pulsating delayed detonation, and tamped detonation scenarios for Type Ia SNs are here addressed by the bolometric, blue, and visual light curves generated by a set of theoretical models. Several correlations between observable quantities and model parameters are found which allow for discrimination between models. Standard and nonstandard models are distinguished by the time-dependence of the photospheric expansion velocity, which is directly measurable by the Doppler shift of spectral lines.
