Compact stars in scalar-tensor theories with a single-well potential and the corresponding theory
Juan M. Z. Pretel, Sergio E. Jorás, Ribamar R. R. Reis +2
The macroscopic properties of compact stars in modified gravity theories can be significantly different from the general relativistic (GR) predictions. Within the gravitational con…
Charged quark stars in metric gravity
Juan M. Z. Pretel, José D. V. Arbañil, Sergio B. Duarte +2
We provide the modified TOV equations for the hydrostatic equilibrium of charged compact stars within the metric gravitational background. We adopt the MIT bag model EoS for…
-gravity quark stars from perturbative QCD
José C. Jiménez, Juan M. Z. Pretel, Eduardo S. Fraga +2
We investigate the structure of quark stars in the framework of gravity using an equation of state for cold quark matter obtained from perturbative QCD, parametrize…
Influence of gravitational waves upon light in the Minkowski background: from null geodesics to interferometry
João C. Lobato, Isabela S. Matos, Lucas T. Santana +2
We have recently derived a manifestly covariant evolution law, under the geometrical optics approximation of the vacuum Maxwell's equations, for the electric field along null geode…
Neutron stars in gravity with conserved energy-momentum tensor: Hydrostatic equilibrium and asteroseismology
Juan M. Z. Pretel, Sergio E. Jorás, Ribamar R. R. Reis +1
We investigate the equilibrium and radial stability of spherically symmetric relativistic stars, considering a polytropic equation of state (EoS), within the framework of …
Influence of gravitational waves upon light. Part II. Electric field propagation and interference pattern in a gravitational wave detector
João C. Lobato, Isabela S. Matos, Lucas T. Santana +2
In this second article of the series, we apply our recently derived equation for the electric field propagation along light rays [arXiv:2004.03496], valid on the electromagnetic ge…
