Simulation of Rotating Black Holes

Languages of publication
Considering the analogy between classical thermodynamic parameters and black hole parameters, the four laws of thermodynamics are reinterpreted for Kerr and Kerr-Newman black holes. A simple model for the dynamic relationships was obtained by considering the surface area of the outer horizon of a Kerr and Kerr-Neumann black hole as the area of a perfect black body. Finding the conditions these black holes should satisfy, the equations were numerically solved and simulated for the Hawking temperature, Hawking radiation and entropy variations of Kerr and Kerr-Newman black holes. The Hawking temperature and Hawking radiation of a given rotating black hole drastically increases at the final stage of the black hole evaporation. In the meantime, the entropy of a rotating black hole drastically decreases through the time. The additional angular momentum and the charge effects gain high Hawking temperatures and high Hawking radiation values for the black holes while these effects reduce the entropy of the black holes.
