Abstract

In this paper we have studied the accretion of phantom energy on a 2 + 1dimensional stationary Banados–Teitelboim–Zanelli BTZ black hole It has already been shown by Babichev et al that for the accretion of phantom energy onto a Schwarzschild black hole the mass of black hole would decrease and the rate of change of mass would be dependent on the mass of the black hole However in the case of 2 + 1dimensional BTZ black hole the mass evolution due to phantom accretion is independent of the mass of the black hole and is dependent only on the pressure and density of the phantom energy We also study the generalized second law of thermodynamics at the event horizon and construct a condition that puts an lower bound on the pressure of the phantom energy
