Non-singular black hole by gravitational decoupling and some thermodynamic properties
Gravitational decoupling allows to obtain new solutions of general relativity. In this paper, we obtain new solutions of the Einstein field equations which describe non-singular black holes. We consider Hayward and Bardeen regular black holes as seed spacetimes and apply gravitational decoupling to...

| description | Gravitational decoupling allows to obtain new solutions of general relativity. In this paper, we obtain new solutions of the Einstein field equations which describe non-singular black holes. We consider Hayward and Bardeen regular black holes as seed spacetimes and apply gravitational decoupling to obtain a new non-singular solution. We show that anisotropic energy-momentum tensor can spoil the regularity condition in the centre of a black hole. We solve the Einstein field equation and obtain new solutions that possess a de Sitter core and have Schwarzschild behaviour in infinity. We also analyse the thermodynamic properties of the obtained solutions. |
