Bulk Viscous Damping of Density Oscillations in Neutron Star Mergers
Bulk Viscous Damping of Density Oscillations in Neutron Star Mergers
In this paper, we discuss the damping of density oscillations in dense nuclear matter in the temperature range relevant to neutron star mergers. This damping is due to bulk viscosity arising from the weak interaction “Urca” processes of neutron decay and electron capture. The nuclear matter is modelled in the …
