Mass and spin constraint on black holes in long GRBs

High Energy Astrophysical Phenomena 2019-12-09 v1

Abstract

We compute the evolution of a quasi-spherical, slowly rotating accretion flow around a black hole, whose mass and spin evolve adequately to the mass-energy transfer through the horizon. Our model is relevant for the central engine driving a long gamma ray burst, that originates from the collapse of a massive star. Our results show how much mass and spin a newly formed black hole should possess during collapsar to launch long GRB.
