Phantom Accretion by Five Dimensional Charged Black Hole

TL;DR

This study investigates how phantom energy accretes onto five-dimensional charged black holes, analyzing the flow dynamics, critical points, and implications for black hole evolution without forming naked singularities.

Contribution

It extends the analysis of phantom accretion from four-dimensional to five-dimensional charged black holes, deriving new equations and critical conditions.

Findings

Phantom energy accretes onto 5D charged black holes for negative flow velocity.

Critical points of accretion are identified, influencing mass-charge ratio.

Accretion does not lead to naked singularities in 5D black holes.

Abstract

This paper deals with the dynamical behavior of phantom field near five dimensional charged black hole. We formulate equations of motion for steady-state spherically symmetric flow of phantom fluids. It is found that phantom energy accretes onto black holes for $u<0$. Further, the location of critical point of accretion are evaluated that leads to mass to charge ratio for 5D charged black hole. This ratio implies that accretion cannot transform a black hole into a naked singularity. We would like to mention here that this work is an irreducible extension of 4D charged black hole.
