Neutron stars with a dark-energy core from the Chaplygin gas
Juan M. Z. Pretel, Mariana Dutra, Sergio B. Duarte
We analyze the effect of a Chaplygin dark fluid (CDF) core on neutron stars (NSs). To address this study, we focus on the relativistic structure of stellar configurations composed…
Dark energy effects on realistic neutron stars
Juan M. Z. Pretel, Sergio B. Duarte, José D. V. Arbañil +2
By considering realistic equations of state (EoSs) to describe the ordinary matter of the stellar crust, in this study, we explore the effect of a dark energy core, made of Chaplyg…
Moment of inertia and compactness of quark stars within the context of gravity
Juan M. Z. Pretel
Within the metric formalism of gravity theories, we investigate the hydrostatic equilibrium structure of compact stars taking into account both isotropic and anisotrop…
Gravitational wave seismology of charged strange stars in the Cowling approximation: the fluid pulsation modes
José D. V. Arbañil, César H. Lenzi, Juan M. Z. Pretel +1
In this work we study, within the framework of Cowling approximation, the effect of the electric charge on the gravitational wave frequency of fluid oscillation modes of strange qu…
Compact stars in Rastall gravity: hydrostatic equilibrium and radial pulsations
Juan M. Z. Pretel, Clésio E. Mota
Within the context of Rastall gravity, we investigate the hydrostatic equilibrium and dynamical stability against radial pulsations of compact stars, where a free parameter mea…
Neutron stars in gravity
Clésio E. Mota, Juan M. Z. Pretel, César O. V. Flores
This study explores the behavior of compact stars within the framework of gravity, focusing on the functional form . The modified Tolman-Oppenh…
Normal oscillation modes and radial stability of neutron stars with a dark-energy core from the Chaplygin gas
Juan M. Z. Pretel, Mariana Dutra, Sergio B. Duarte
As a potential candidate for the late-time accelerating expansion of the Universe, the Chaplygin gas and its generalized models have significant implications to modern cosmology. I…
Universal relations for anisotropic interacting quark stars
Juan M. Z. Pretel, Chen Zhang
Interacting quark stars, which are entirely composed of interacting quark matter including perturbative QCD corrections and color superconductivity, can meet constraints from vario…
