Implications of turbulence for jets in core-collapse supernova explosions

TL;DR

This paper explores how turbulence in core-collapse supernovae can lead to the formation of accretion disks and jets, potentially driving supernova explosions without shock revival, thus supporting the jittering jets explosion mechanism.

Contribution

It demonstrates that turbulence can form accretion disks and jets around neutron stars, providing a new pathway for supernova explosions independent of shock revival.

Findings

Turbulence can create accretion disks and belts around neutron stars.

Jets launched from these disks can contribute significantly to explosion energy.

Jittering jets mechanism is strengthened as a viable supernova explosion model.

Abstract

We show that turbulence in core collapse supernovae (CCSNe) which has been shown recently to ease shock revival might also lead to the formation of intermittent thick accretion disks, or accretion belts, around the newly born neutron star (NS). The accretion morphology is such that two low density funnels are formed along the polar directions. The disks then are likely to launch jets with a varying axis direction, i.e., jittering-jets, through the two opposite funnels. The energy contribution of jets in this jittering jets mechanism might result in an explosion energy of E>10^51erg, even without reviving the stalled shock. We strengthen the jittering jets mechanism as a possible explosion mechanism of CCSNe.
