Theoretical models for supernovae

The results of numerical simulations of supernova explosions are presented. Particular emphasis is given to: (1) the nucleosynthesis expected from intermediate mass (10sub solar or = M or = 100 Msub solar) Type II supernovae and detonating white dwarf models for Type I supernovae; (2) a realistic estimate of the gamma-line fluxes expected from this nucleosynthesis; (3) the continued evolution, in one and two dimensions, of intermediate mass stars wherein iron core collapse does not lead to a strong, mass-ejecting shock wave; and (4) the evolution and explosion of vary massive stars (M 100 Msub solar of both Population I and III.
