A. Beesham, S. G. Ghosh
TL;DR
This paper investigates the formation of naked singularities during the gravitational collapse of charged null fluids in a deSitter universe, identifying conditions under which these singularities can occur, extending previous uncharged models.
Contribution
It provides a detailed analysis of naked singularity formation in charged Vaidya-deSitter spacetime, including necessary conditions and generalization of uncharged solutions.
Findings
Naked singularities can form under specific conditions in charged Vaidya-deSitter collapse.
The analysis recovers known results for uncharged cases.
Conditions for naked singularity formation are explicitly characterized.
Abstract
We study the occurrence of naked singularities in the spherically symmetric collapse of a charged null fluid in an expanding deSitter background - a piece of charged Vaidya-deSitter spacetime. The necessary conditions for the formation of a naked singularity are found. The results for the uncharged solutions can be recovered from our analysis.
