Scientific paper

Recent models of Type I supernovae (SNI) are discussed. The observational constraints, including the population, composition, kinematics, compact remnant, light curve, and galactic iron abundance are addressed, and it is concluded that the population of SNI is an open question. The results of studies of light curves for recent models of SNI's are assessed, and the effects of constraints on white dwarf models and models with extended helium envelopes are discussed. It is concluded that models involving central carbon ignition and deflagration as well as those involving extended helium envelopes are promising, but models combining both aspects are unworkable at this point. Current developments in studies of Rayleigh Taylor instability and in deflagrating models are presented. Finally, iron production by SNI's, the effect on the upper atmosphere of gamma rays from SNI's, and light element synthesis in helium envelopes are briefly discussed.
