抄録

We examine explosive nucleosynthesis during a delayed neutrino-driven, supernova explosion aided by standing accretion shock instability, based on two-dimensional hydrodynamic simulations of the explosion of a 15 M⊙progenitor.We find that abundance pattern of the supernova ejecta is similar to that of the solar system, for cases with high explosion energies of ≃ 1051ergs. Aspherical distribution of Fe, Si, and O, which is observed in a nearby core-collapse SN remnant such as Cas A, is obtained in spite of the explosion of the non-rotating, spherical progenitor.
