Keywords:

Black hole solutions play a fundamental role in understanding the structure of spacetime in general relativity and its extensions. Modifications of classical solutions often introduce additional parameters that encode deviations from Einstein gravity or effective matter couplings. In this paper, we consider a charged and static spherically symmetric spacetime characterized by an additional dimensionless parameter. Such a parameter may arise in effective gravitational theories or phenomenological modifications of general relativity.

Abstract

In this work, we investigate a static and spherically symmetric charged black hole solution in the presence of a dimensionless parameter . Starting from the Einstein-Maxwell field equations, we derive an exact analytical form of the metric function. The horizon structure is analyzed in detail by solving the corresponding cubic equation. Thermodynamic quantities such as surface gravity and Hawking temperature are also discussed. The obtained solution reduces to the standard Reissner-Nordström black hole in the appropriate limit.
