Thermodynamics of a modified Schwarzschild white hole in the presence of a cosmological constant
Amos S. Kubeka, Alireza Amani
Abstract
In this paper, we modify the usual Schwarzschild white hole in the presence of the cosmological constant. We then study its [Formula: see text] criticality, heat capacity, derive its equation of state, and then its stability conditions. In the process, we find that the thermal properties of the modified Schwarzschild white hole are not that of the usual Schwarzschild white hole as first stated in the literature by Stephen Hawking and then confirmed by others, but in fact, they are analogous to the thermal properties of our the universe.
