Free-falling test particles in a charged Kalb-Ramond black hole: gravitational Doppler effect and tidal forces
Daniela S. J. Cordeiro, Ednaldo L. B. Junior, José Tarciso S. S. Junior +5
Space-times exhibiting spontaneous Lorentz symmetry-breaking have recently attracted much attention, with Kalb-Ramond (KR) gravity providing a notable example. In this context, we…
Dyonic regular black bounce solutions in General Relativity
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +3
This work explores dyonic black bounce (BB) solutions within the framework of General Relativity (GR), coupled with nonlinear electrodynamics (NLED) and scalar fields (SFs). Previo…
Novel electrically charged wormhole, black hole and black bounce exact solutions in hybrid metric-Palatini gravity
Gabriel I. Róis, José Tarciso S. S. Junior, Francisco S. N. Lobo +1
This paper presents a systematic exploration of exact solutions for electrically charged wormholes, black holes, and black bounces within the hybrid metric-Palatini gravity (HMPG)…
Charged black hole solutions in gravity coupled to nonlinear electrodynamics
Gabriel I. Róis, José Tarciso S. S. Junior, Francisco S. N. Lobo +2
In this work, we investigate static and spherically symmetric black hole solutions in gravity, where is the curvature scalar and is the trace of the energy-momentu…
