Naked Singularity, Black-hole and the Mass Loss in a Spherically Symmetric Gravitational Collapse

TL;DR

This paper investigates the energy radiated during spherically symmetric gravitational collapse, comparing naked singularity and black-hole outcomes, and finds that black-hole formation can release more energy than naked singularities.

Contribution

It provides a comparative analysis of energy radiation in collapse scenarios ending in naked singularities versus black holes within general relativity.

Findings

Black-hole collapse can release more energy than naked singularity collapse.

Total energy radiated is limited in naked singularity formation.

Black-hole formation results in higher mass loss in the studied cases.

Abstract

A distinguishable physical property between a naked singularity and a black-hole, formed during a gravitational collapse has important implications for both experimental and theoretical relativity. We examine the energy radiated during the spherically symmetric Gravitational collapse in this context within the framework of general relativity. It is shown that total energy radiated(Mass Loss) during the collapse ending in a naked singularity scenario cannot be more than the case when a collapse scenario ends in a black-hole. In cases of interest(for example stars having same mass, size, and internal composition) considered here the total energy released in the collapse ending in a black hole can be considerably more than the case otherwise.
