Findings

Black hole singularities can be avoided using specific nonlinear electrodynamics.

The final density depends only on the quintessential density term and mass.

The approach modifies the internal structure of black holes without singularities.

Abstract

We propose a way to remove black hole singularities by using a particular nonlinear electrodynamics Lagrangian that has been recently used in various astrophysics and cosmological frameworks. In particular, we adapt the cosmological analysis discussed in a previous work to the black hole physics. Such analysis will be improved by applying the Oppenheimer-Volkoff equation to the black hole case. At the end, fixed the radius of the star, the final density depends only on the introduced quintessential density term $\rho_{\gamma}$ and on the mass.
