Can Population III Stars at High Redshifts produce GRB's?

TL;DR

This paper argues that Population III stars with about 500 solar masses at high redshifts are unlikely to produce gamma ray bursts because their core collapse temperatures are insufficient for gamma ray emission.

Contribution

It provides a theoretical analysis showing that high-mass Population III stars do not generate GRBs due to inadequate core collapse temperatures.

Findings

High-mass Population III stars do not produce GRBs.

Core collapse temperatures in these stars are insufficient for gamma ray emission.

Supports the idea that not all massive star collapses result in GRBs.

Abstract

Gamma ray bursts are the most luminous physical phenomena in the universe, consisting of flashes of gamma rays that last from seconds to hours. There have been attempts to observe gamma ray bursts, for example, from population III stars of about 500 solar mass at high redshifts. Here we argue that collapse of such high mass stars does not lead to gamma ray burst as their core collapse temperatures are not sufficient to produce gamma rays, leading to GRBs.
