Effects of light-mass fermionic dark matter on the equilibrium and stability of white dwarfs
G. A. Carvalho, J. D. V. Arbañil, J. G. Coelho
White dwarfs (WDs) can be used as laboratories to test strong gravity and high-density regimes, once their equation of state is not so uncertain as the one of neutron stars. This m…
Fluid pulsation modes and tidal deformability of anisotropic strange stars in light of the GW event
José D. V. Arbañil, Cesar V. Flores, César H. Lenzi +1
The effects of the anisotropy on the fluid pulsation modes adopting the so-called Cowling approximation and tidal deformability of strange quark stars are investigated by using the…
Phase transition and stiffer core fluid in neutron stars: Effects on stellar configurations, dynamical stability, and tidal deformability
José D. V. Arbañil, Lucas S. Rodrigues, César H. Lenzi
In this work, we investigate the influence of the phase transition and a stiffer fluid in neutron stars' cores on the static equilibrium configuration, dynamical stability, and tid…
Radial stability of anisotropic strange quark stars
José D. V. Arbañil, M. Malheiro
The influence of the anisotropy in the equilibrium and stability of strange stars is investigated through the numerical solution of the hydrostatic equilibrium equation and the rad…
