Post-explosion Evolution of Core-collapse Supernovae

We investigate the post-explosion phase in core-collapse supernovae with 2D hydrodynamical simulations and a simple neutrino treatment. The latter allows us to perform 46 follow evolution of 32 explosion models during several seconds. present broad study based on three progenitors (11.2, 15, 27 M?), different heating efficiencies, various rotation rates. show that first seconds after shock revival determine final energy, remnant mass, properties ejected matter. Our results suggest continued mass accretion increases energy even at late times. link late-time initial conditions such as strength deformation time. Only some our develop neutrino-driven wind (NDW) survives for This indicates NDWs are not standard feature expected every successful explosion. Even if treatment is simple, we estimate nucleosynthesis exploding 15 M? progenitor correcting energies luminosities get more realistic electron fraction.
