Rotating Regular Black Hole Solution

TL;DR

This paper derives a rotating regular black hole solution from a static charged black hole metric using the Newman-Janis algorithm, showing the solution remains regular and analyzing how angular momentum affects the horizon structure.

Contribution

It introduces a rotating regular black hole solution based on the Ayon-Beato-Garcia metric, extending static solutions to include rotation while maintaining regularity.

Findings

The rotating solution remains regular without singularities.

The critical charge for horizon merging decreases with increasing angular momentum.

Rotation influences the horizon structure and critical parameters of the black hole.

Abstract

Based on the Newman-Janis algorithm the Ayon-Beato-Garcia spacetime metric of the regular spherically symmetric, static and charged black hole has been converted into rotational form. It is shown that the derived solution for rotating regular black hole is regular and the critical value of the electric charge $Q$ for which two horizons merge into one sufficiently decreases in the presence of nonvanishing angular momentum $a$ of the black hole.
