Hydrodynamical Collapse of Neutron Stars due to Hadron-Quark Phase Transition
G. F. Marranghello, J. C. N. de Araujo, O. D. Miranda
We present studies of the collapse of neutron stars that undergo a hadron-quark phase transition. A spherical Lagrangian hydrodynamic code has been written. As initial condition we…
Gravitational wave background from neutron star phase transition
J. C. N. de Araujo, G. F. Marranghello
We study the generation of a stochastic gravitational wave (GW) background produced by a population of neutron stars (NSs) which go over a hadron-quark phase transition in its inne…
A solution for galactic disks with Yukawian gravitational potential
J. C. N. de Araujo, O. D. Miranda
We present a new solution for the rotation curves of galactic disks with gravitational potential of the Yukawa type. We follow the technique employed by Toomre in 1963 in the study…
Wave polarizations for a beam-like gravitational wave in quadratic curvature gravity
E. C. de Rey Neto, J. C. N. de Araujo, O. D. Aguiar
We compute analytically the tidal field and polarizations of an exact gravitational wave generated by a cylindrical beam of null matter of finite width and length in quadratic curv…
