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…
CMB Polarization and Theories of Gravitation with Massive Gravitons
Dennis Bessada, Oswaldo D. Miranda
We study in this paper three different theories of gravitation with massive gravitons - the modified Fierz-Pauli (FP) model, Massive Gravity and the bimetric theory proposed by Vis…
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…
Detectability of f-mode Unstable Neutron Stars by the Schenberg Spherical Antenna
J. C. N. de Araujo, O. D. Miranda, O. D. Aguiar
The Brazilian spherical antenna (Schenberg) is planned to detect high frequency gravitational waves (GWs) ranging from 3.0 kHz to 3.4 kHz. There is a host of astrophysical sources…
