Black hole mass decreasing due to phantom energy accretion

TL;DR

This paper presents a solution for dark energy accretion onto black holes, showing that phantom energy causes black hole masses to decrease and tend to zero in a universe heading towards the Big Rip.

Contribution

It generalizes the Michel solution to include dark energy accretion, demonstrating mass decrease due to phantom energy.

Findings

Black hole mass decreases with phantom energy accretion.

All black holes tend to zero mass near the Big Rip.

The solution applies to relativistic perfect fluid accretion onto Schwarzschild black holes.

Abstract

Solution for a stationary spherically symmetric accretion of the relativistic perfect fluid with an equation of state p(rho) onto the Schwarzschild black hole is presented. This solution is a generalization of Michel solution and applicable to the problem of dark energy accretion. It is shown that accretion of phantom energy is accompanied with the gradual decrease of the black hole mass. Masses of all black holes tend to zero in the phantom energy universe approaching to the Big Rip.
