Post-explosion evolution of core-collapse supernovae

Understand

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 simulations and follow the evolution of the 32 successful explosions during several seconds.
• We present a broad study based on three progenitors (11.2 $M_\odot$, 15 $M_\odot$, and 27 $M_\odot$), different neutrino-heating efficiencies, and various rotation rates.
• We show that the first seconds after shock revival determine the final explosion energy, remnant mass, and properties of ejected matter.
