Probing internal dissipative processes of neutron stars with gravitational waves during the inspiral of neutron star binaries
We study the impact of out-of-equilibrium, dissipative effects on the dynamics of inspiraling
neutron stars. We find that modeling dissipative processes (such as those from the stars …

A constraint on the dissipative tidal deformability of neutron stars
The gravitational waves emitted by neutron star binaries probe the physics of matter at
supranuclear densities. During the late inspiral, tidal deformations raised on each star by the …

Estimate for the bulk viscosity of strongly coupled quark matter using perturbative QCD and holography
Modern hydrodynamic simulations of core-collapse supernovae and neutron-star mergers
require knowledge not only of the equilibrium properties of strongly interacting matter, but …

Dissipative tidal effects to next-to-leading order and constraints on the dissipative tidal deformability using gravitational wave data
Dissipative tidal interactions can be used to probe the out-of-equilibrium physics of neutron
stars using gravitational wave observations. In this paper, we present the first post …
