We find multicenter (Majumdar-Papapetrou type) solutions of Eddington-inspired Born-Infeld gravity coupled to electromagnetic fields governed by a Born-Infeld-like Lagrangian. We construct the general solution for an arbitrary number of centers [...]texto impreso
Afonso, Victor I. ; Olmo, Gonzalo J. ; Orazi, Emanuele ; Rubiera García, Diego | IOP Publishing | 2019-12Taking advantage of a previously developed method, which allows to map solutions of General Relativity into a broad family of theories of gravity based on the Ricci tensor (Ricci-based gravities), we find new exact analytical scalar field soluti[...]texto impreso
Guerrero Roman, Merce ; Mora Pérez, Gerardo ; Olmo, Gonzalo J. ; Orazi, Emanuele ; Rubiera García, Diego | IOP publishing ltd | 2020-07We find an exact, rotating charged black hole solution within Eddington-inspired Born-Infeld gravity. To this end we employ a recently developed correspondence or mapping between modified gravity models built as scalars out of contractions of th[...]texto impreso
Lobo, Francisco S. N. ; Olmo, Gonzalo J. ; Orazi, Emanuele ; Rubiera García, Diego ; Rustam, Azmat | Amer Physical Soc | 2020-11-06We study the structure and stability of traversable wormholes built as (spherically symmetric) thin shells in the context of Palatini f(R) gravity. Using a suitable junction formalism for these theories we find that the effective number of degre[...]
