Projecting the likely importance of weak-interaction-driven bulk viscosity in neutron star mergers
In this work, we estimate how much bulk viscosity driven by Urca processes is likely to affect
the gravitational wave signal of a neutron star coalescence. In the late inspiral, we show that …

Emergence of microphysical bulk viscosity in binary neutron star postmerger dynamics
In nuclear matter in isolated neutron stars, the flavor content (eg, proton fraction) is subject to
weak interactions, establishing flavor (β-) equilibrium. However, there can be deviations …
