Exploding SNe with jets: time-scales

TL;DR

This paper uses hydrodynamical simulations to compare the time-scales of jet-driven supernova explosions with the delayed neutrino mechanism, highlighting significant energy differences.

Contribution

It provides a detailed analysis of the time-scales in the jittering-jets model and compares them to the neutrino mechanism, emphasizing the energy discrepancy.

Findings

Jet-driven explosions reach the required energy more efficiently.

Delayed neutrino mechanism produces significantly less energy.

Time-scales differ notably between the two explosion models.

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.
