Physical models for type I supernovae and the distance scale
The degenerate carbon deflagration models for Type I supernovae are consistent with a variety of observations of light curves and spectra. Progenitor systems consisting of carbon/oxygen white dwarfs with normal companions or of binary white dwarfs are discussed and limits are established on the amount of 56Ni which can be ejected in models which match the observations. The luminosity at maximum light in these models is proportional to the amount of nickel ejected, and hence limits can be set on the distance scale and H0. If the carbon deflagration model is correct, then 0.4 < H0/(100 km/s/Mpc) <0.7.
