Scientific paper
The investigation considered has the purpose to compare models involving radioactivity with the detailed observations of Type I supernovae (SN I) near maximum light. The supernova models presented involve a combination of analytical and numerical calculations. The numerical computations were performed with the same radiation-hydrodynamics code that was used by Chevalier (1976) to compute the properties of Type II supernovae. The new features of the present work involve the explosion mechanism, the structure of the progenitor star, the composition of the gas, and the energy deposition into the gas due to radioactivity. Attention is given to the density profile, the gamma-ray energy deposition, the mean opacity of the gas, and the remnants of Type I supernovae.
