Regular fluid of strings black hole with non trivial core and asymptotic structure by gravitational decoupling
Milko Estrada, Luis C. N. Santos, Leonardo G. Barbosa
Cloud-of-strings (CS) geometries provide an effective description of one-dimensional string distributions. However, their central singularity cannot be removed through the standard…
Scalar Bosons with Coulomb Potentials in a Space with Dual Topological Defects in Rainbow Gravity
L. G. Barbosa, J. V. Zamperlini, L. C. N. Santos
This work studies the relativistic quantum dynamics of scalar bosons in a spacetime containing both a cosmic string and a global monopole within the framework of Rainbow Gravity. A…
Kiselev black strings in gravity
L. C. N. Santos, L. G. Barbosa, C. C. Barros
In this work, we investigate exact black string solutions in the context of gravity. Adopting the specific form , we consider an anisotropic Kiselev flu…
Charged scalar boson in Melvin universe
L. G. Barbosa, L. C. N. Santos, J. V. Zamperlini +2
This work investigates the dynamics of a charged scalar boson in the Melvin universe by solving the Klein-Gordon equation with minimal coupling in both inertial and non-inertial fr…
Strongly Interacting Quark Matter in Massive Quark Stars
Adamu Issifu, Franciele M. da Silva, Luis C. N. Santos +2
This paper investigates the properties of strongly coupled matter at high baryon densities (\(Ï_B\)) in quark stars (QSs). The QS model is based on the density-dependent quark mas…
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…
