-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…
Influence of gravitational waves upon light. Part I. Null geodesics, radar distance and frequency shift
João C. Lobato, Isabela S. Matos, Lucas T. Santana +2
We explore different facets of the action of linearized gravitational waves in Minkowski spacetime background upon light, under the electromagnetic geometrical optics limit, coveri…
