Gauge-invariant perturbations of relativistic non-perfect fluids in spherical spacetime
David DÃaz-Guerra, Conrado Albertus, Prasanta Char +1
Astrophysical compact objects are usually studied using a perfect fluid model. However, in astrophysical processes out-of-equilibrium, dissipative effects become important to descr…
