Ultracompact anisotropic stars and gravastars in general relativity
Prajwal Hassan Puttasiddappa, Nora Bretón, Santiago Esteban Perez Bergliaffa
We study static, spherically symmetric ultracompact objects in General Relativity with anisotropic stress. Using the covariant anisotropic equation of state and assuming homogeneou…
Nonlinear electrodynamics in Kerr-Newman-NUT- spacetime: exact solutions, horizons, and energy conditions
Oscar Galindo-Uriarte, Nora Breton, Claus Lämmerzahl +1
We construct two exact nonlinear-electrodynamic generalizations of the Kerr-Newman-NUT- spacetime. Imposing alignment between the principal directions of the electromagnetic fie…
Four-function generalization and separable structures of the Plebanski spacetime with sources
Alfonso S. Acevedo, Nora Breton
We determine a four-function generalization of the Plebanski spacetime, depending on three arbitrary functions of the radial coordinate, and one function on the angular coordinate.…
Comparative of light propagation in Born-Infeld, Euler-Heisenberg and ModMax nonlinear electrodynamics
Elda Guzman-Herrera, Ariadna Montiel, Nora Breton
We compare light propagation through an intense electromagnetic background as described by three different nonlinear electrodynamics: Born-Infeld (BI), Euler-Heisenberg (EH), and M…
Nonlinear electromagnetic generalization of the Kerr-Newman solution with cosmological constant
Oscar Galindo-Uriarte, Nora Breton
We present the two exact solutions of the Einstein-Nonlinear electrodynamics equations that generalize the Kerr-Newman solution. We determined the generalized electromagnetic poten…
Energy extraction from the Reissner-Nordström de Sitter black hole
A. Baez, Nora Breton, I. Cabrera-Munguia
The energy extraction from an electrostatic black hole by the decay or splitting of electrically charged particles is analyzed. We determine the energetic conditions that make the…
