Quiescence and late time activity in collapsars due to critical angular momentum distributions

TL;DR

This paper investigates how variations in stellar angular momentum distributions can cause quiescent periods and late-time activity in long gamma-ray bursts, providing insights into their complex temporal behavior.

Contribution

It introduces a model linking angular momentum profiles in collapsars to neutrino luminosity variability and quiescent episodes in LGRBs.

Findings

Angular momentum distributions influence neutrino luminosity variability.

Different stellar angular momentum profiles can produce quiescent periods.

The model explains late-time activity in long gamma-ray bursts.

Abstract

Even thought a large amount of long gamma ray bursts (LGRBs) present quiescent periods, their origin remains unclear. In this talk, it is shown how different angular momentum distributions, as a function of the stellar radius), can lead to neutrino luminosity variability and the possibility of quiescent epochs in LGRBs.
