Real particle geodesics and thermodynamics of a black hole in Regular Schwarzschild-Anti de Sitter space-time

In this work, we illustrate the geodesics of real particles obtained numerically in a Regular Schwarzschild Anti-de Sitter (RSch-AdS) space-time. The behavior of these geodesics are considered depending on variation of effective parameters such as mass distribution, angular momentum and cosmological constant. Also, using the laws of thermodynamics of black holes, we will study and discuss some aspect of black hole (BH) described by this spacetime such as temperature, entropy, heat capacity and Gibbs free energy.Comment: 22 pages, 26 figure

Thermodynamics of the Schwarzschild and the Reissner–Nordström black holes with quintessence

In this paper, we study the thermodynamics of the Schwarzschild and the Reissner–Nordström black holes surrounded by quintessence. By using the thermodynamical laws of the black holes, we derive the thermodynamic properties of these black holes and we compare the results with each other. We investigate the mass, temperature and heat capacity as functions of entropy for these black holes. We also discuss the equation of state of the Schwarzschild and the Reissner–Nordström black holes surrounded by quintessence
