White dwarf structure in gravity: beyond the Chandrasekhar mass limit
Edson Otoniel, Juan M. Z. Pretel, Clésio E. Mota +3
In this work, we investigate the relativistic structure of white dwarfs (WDs) within the framework of modified gravity theory , which introduces a non-mi…
The sound of quintessence: analogue Kiselev acoustic black holes
Luis C. N. Santos, H. S. Vieira, Franciele M. da Silva +1
In this work, we demonstrate that the geometry of a spherically symmetric black hole surrounded by a Kiselev anisotropic fluid can be effectively mimicked by an experimental setup…
Black holes as gravitational mirrors
L. C. N. Santos, F. M. da Silva, C. R. Muniz +1
Retrolensing is a gravitational lensing effect in which light emitted by a background source is deflected by a black hole and redirected toward the observer after undergoing nearly…
Bound and Scattering States in a Spacetime with Dual Topological Defects: Cosmic String and Global Monopole
L. G. Barbosa, L. C. N. Santos, J. V. Zamperlini +1
This paper explores the relativistic quantum motion of scalar bosons in the presence of mixed topological defects: cosmic strings and global monopoles. The Klein-Gordon equation wi…
Kiselev black holes in gravity
L. C. N. Santos, F. M. da Silva, C. E. Mota +2
We obtain new exact solutions for the gravitational field equations in the context of gravity, thereby obtaining different classes of black holes surrounded by fluids, tak…
Rapidly rotating neutron stars in gravity
F. M. da Silva, L. C. N. Santos, C. E. Mota +2
In this work, we study the influence of gravity on rapidly rotating neutron stars. First we discuss the main aspects of this modified theory of gravity where the gravitati…
Generalized Rastall's gravity and its effects on compact objects
Clésio E. Mota, Luis C. N. Santos, Franciele M. da Silva +3
We present a generalization of Rastall's gravity in which the conservation law of the energy-momentum tensor is altered, and as a result, the trace of the energy-momentum tensor is…
