Title

Abstract

The important result of the iron core collapse simulation is the formation of the convectively unstable regions in the center and in the region of the accretion. Usually investigators study the thin region of the accretion leading to the small-scale convective instability. But detailed calculations of the collapse with the neutrino transport give us also large region near the center suitable for the convective insatiability during 10 ms. In the frame of 3D hydrodynamic simulations with taking into account self-gravity I illustrate the possibility of the developing of the large-scale convection during such short time. Another important result from the viewpoint supernova explosion is the huge neutrino energy in the degenerate convective bubble about 100 MeV in compare with the thermal neutrino 10 MeV from the neutrino-sphere. Large neutrino energy is suitable for the explanation of the supernova explosion.
