Bulk Viscosity of Relativistic Matter in Neutron-Star Mergers
Mark Alford, Arus Harutyunyan, Armen Sedrakian
We discuss the bulk viscosity of hot and dense matter arising from weak-interaction direct Urca processes. We consider two regimes of interest: (a) the neutrino-transparent…
Equation of state and composition of proto-neutron stars and merger remnants with hyperons
Armen Sedrakian, Arus Harutyunyan
Finite-temperature equation of state (EoS) and the composition of dense nuclear and hypernuclear matter under conditions characteristic of neutron star binary merger remnants and s…
Bulk Viscous Damping of Density Oscillations in Neutron Star Mergers
Mark Alford, Arus Harutyunyan, Armen Sedrakian
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 viscosi…
On the importance of resistivity and Hall effect in MHD simulations of binary neutron star mergers
Arus S. Harutyunyan
We examine the range of rest-mass densities, temperatures and magnetic fields involved in simulations of binary neutron star mergers (BNSM) and identify the conditions under which…
Bulk viscosity of baryonic matter with trapped neutrinos
Mark Alford, Arus Harutyunyan, Armen Sedrakian
We study bulk viscosity arising from weak current Urca processes in dense baryonic matter at and beyond nuclear saturation density. We consider the temperature regime where neutrin…
Bulk Viscosity of Hot Quark Plasma from Non-Equilibrium Statistical Operator
Arus Harutyunyan, Armen Sedrakian
We provide a discussion of the bulk viscosity of two-flavor quark plasma, described by the Nambu--Jona-Lasinio model, within the framework of Kubo-Zubarev formalism. This discussio…
