Exploding SNe with jets: time-scales

Abstract

We perform hydrodynamical simulations of core collapse supernovae (CCSNe) with a cylindrically-symmetrical numerical code (FLASH) to study the inflation of bubbles and the initiation of the explosion within the frame of the jittering-jets model. We study the typical time- scale of the model and compare it to the typical time-scale of the delayed neutrino mechanism. Our analysis shows that the explosion energy of the delayed neutrino mechanism is an order of magnitude less than the required 10^51 erg.Comment: To appear in Death of Massive Stars: Supernovae and Gamma-Ray Bursts, Proceedings IAU Symposium No. 279, 2012, eds.
