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…
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…
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…
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…
