Abstract: Through gravitational decoupling using the extended minimal geometric deformation, a new family of static and rotating “hairy” black holes is provided. The background of these models is a generic Schwarzschild metric containing as special cases, the Schwarzschild, Schwarzschild-dS, Reissner-Nordstrom and Reissner-Nordstrom-dS black holes. Assuming the Kerr-Schild condition and a general equation of state, the unknown matter sector is solved given rise to black hole space-times without a Cauchy horizon, transforming the original time-like singularity of the Reissner-Nordstrom and Reissner-Nordstrom-dS black holes into a space-like singularity. This fact is preserved for the rotating version of all these solutions.
The article presents a new family of black hole solutions obtained through gravitational decoupling using the extended minimal geometric deformation. These solutions exhibit “hair” in the form of additional structure and dynamics within the black hole.
Conclusions
- A family of static and rotating “hairy” black holes is provided through gravitational decoupling.
- The solutions are derived from a generic Schwarzschild metric, encompassing Schwarzschild, Schwarzschild-dS, Reissner-Nordstrom, and Reissner-Nordstrom-dS black holes as special cases.
- The unknown matter sector is solved under the assumption of the Kerr-Schild condition and a general equation of state.
- The resulting black hole space-times lack a Cauchy horizon and transform the Reissner-Nordstrom and Reissner-Nordstrom-dS black holes’ original time-like singularity into a space-like singularity.
- These findings hold true for the rotating versions of the solutions as well.
