Breakdown of Hydrodynamic Universality in Neutron Star Oscillations
Gabriel S. Denicol, Amanda Guerrieri, João V. M. Muniz +2
Hydrodynamic universality refers to the property that different formulations of relativistic dissipative hydrodynamics yield identical predictions in the asymptotic long-wavelength…
Radial Oscillations of Viscous Stars at Finite Temperature
Amanda Guerrieri, Gabriel S. Rocha, Gabriel S. Denicol +1
We study the radial oscillation spectrum of relativistic stars within Israel-Stewart and Navier-Stokes theories, extending previous analyses to include heat diffusion and a thermod…
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…
Relaxation Time Approximation for a multi-species relativistic gas
Gabriel S. Rocha, Gabriel S. Denicol
We generalize a recent prescription for the relaxation time approximation for the relativistic Boltzmann equation for systems with multiple particle species at finite temperature.…
Branch-cut in the shear-stress response function of massless with Boltzmann statistics
Gabriel S. Rocha, Isabella Danhoni, Kevin Ingles +2
Using an analytical result for the eigensystem of the linearized collision term for a classical system of massless scalar particles with quartic self-interactions, we show that the…
