Deformed neutron stars
J. T. Quartuccio, P. H. R. S. Moraes, J. D. V. Arbañil
We present solutions for non-spherically symmetric neutron stars. We begin by deriving the Tolman-Oppenheimer-Volkoff equations from a parameterized metric that takes into account…
Gravitational wave asteroseismology of dark matter hadronic stars
C. V. Flores, C. H. Lenzi, M. Dutra +2
The influence of the dark matter mass~() and the Fermi momentum~($k_{F}^{\dm}$) on the -mode oscillation frequency, damping time parameter, and tidal deformability of had…
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…
Tidal deformability and radial oscillations of anisotropic polytropic spheres
José D. V. Arbañil, Grigoris Panotopoulos
We compute the equilibrium, the fundamental eigenfrequency of oscillations modes, and quadrupolar tidal deformability of anisotropic polytropic spheres. These studies are respectiv…
Incompressible relativistic spheres: Electrically charged stars, compactness bounds, and quasiblack hole configurations
José D. V. Arbañil, José P. S. Lemos, Vilson T. Zanchin
We investigate the properties of relativistic star spheres made of an electrically charged incompressible fluid, generalizing, thus, the Schwarzschild interior solution. The invest…
