On the variable-charged black holes embedded into de Sitter space: Hawking's radiation

TL;DR

This paper investigates the Hawking radiation process for variable-charged Reissner-Nordstrom and Kerr-Newman black holes embedded in de Sitter space, focusing on how charge variation affects evaporation.

Contribution

It introduces a model where black hole charge varies with radius, analyzing its impact on Hawking radiation in a de Sitter background.

Findings

Charge variation influences Hawking evaporation rates.

Embedded black holes exhibit modified radiation characteristics.

The study provides insights into black hole thermodynamics with variable charge.

Abstract

In this paper we study the Hawking evaporation of masses of variable-charged Reissner-Nordstrom and Kerr-Newman, black holes embedded into the de Sitter universe by considering the charge to be function of radial coordinate of the spherically symmetric metric.
