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)…
Periodical orbits and waveforms with spontaneous Lorentz symmetry-breaking in Kalb-Ramond gravity
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +4
In this paper, we study time-like geodesics around a spherically symmetric black hole in Kalb-Ramond (KR) gravity, characterized by the parameter , which induces spontaneous Lor…
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…
Constraints on the -parameter for the vacuum solution of Cotton gravity with geodesics and shadows
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +4
We consider a recently introduced extension of General Relativity dubbed as Cotton gravity (CG), based on the use of the Cotton tensor, to estimate the size of a new constant a…
Black bounces in Cotton gravity
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +4
Recently, J. Harada proposed a theory relating gravity to the Cotton tensor, dubbed as ''Cotton gravity'' (CG). This is an extension of General Relativity such that every solution…
Black bounces in conformal Killing gravity
José Tarciso S. S. Junior, Francisco S. N. Lobo, Manuel E. Rodrigues
In this work, we analyse black bounce solutions in the recently proposed ``Conformal Killing gravity'' (CKG), by coupling the theory to nonlinear electrodynamics (NLED) and scalar…
Gravitational lensing of a Schwarzschild-like black hole in Kalb-Ramond gravity
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +4
In this paper, we investigate the gravitational lensing effect for the Schwarzschild-like black hole spacetime in the background of a Kalb-Ramond (KR) field proposed in [K. Yang et…
Spontaneous Lorentz symmetry-breaking constraints in Kalb-Ramond gravity
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +4
In this work, we study timelike and lightlike geodesics in Kalb-Ramond (KR) gravity around a black hole with the goal of constraining the Lorentz symmetry-breaking parameter . T…
Black holes and regular black holes in coincident gravity coupled to nonlinear electrodynamics
José Tarciso S. S. Junior, Francisco S. N. Lobo, Manuel E. Rodrigues
In this work, we consider an extension of the symmetric teleparallel equivalent of General Relativity (STEGR), namely, gravity, by including a boundary term $\mathb…
Observations on the massive particle surface method
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +3
The geodesic method has played a crucial role in understanding the circular orbits generated by compact objects, culminating in the definition of the photon sphere, which was later…
