Radial Oscillations of Viscous Neutron Stars: Zero Diffusion Case
Raissa F. P. Mendes, Amanda Guerrieri, João V. M. Muniz +2
The spectrum of radial oscillations of neutron stars is systematically studied within two frameworks of viscous relativistic hydrodynamics: the relativistic Navier-Stokes and Israe…

On the phase transition mechanism of spontaneous scalarization
João Vitor M. Muniz, Néstor Ortiz, Raissa F. P. Mendes
In certain modified gravity theories that include additional scalar degrees of freedom, compact objects such as black holes and neutron stars may undergo a process known as spontan…
