Simulating bulk viscosity in neutron stars. II. Evolution in spherical symmetry
Giovanni Camelio, Lorenzo Gavassino, Marco Antonelli +2
Out-of-equilibrium reactions between different particle species are the main processes contributing to bulk viscosity in neutron stars. In this work, we numerically compare three d…
Simulating bulk viscosity in neutron stars. I. Formalism
Giovanni Camelio, Lorenzo Gavassino, Marco Antonelli +2
The faithful inclusion of the effects of bulk viscosity induced by the presence of chemical reactions is an important issue for simulations of core-collapse supernovae, binary neut…
Extending Israel and Stewart hydrodynamics to relativistic superfluids via Carter's multifluid approach
Lorenzo Gavassino, Marco Antonelli, Brynmor Haskell
We construct a relativistic model for bulk viscosity and heat conduction in a superfluid. Building on the principles of Unified Extended Irreversible Thermodynamics, the model is d…
Thermodynamic stability implies causality
Lorenzo Gavassino, Marco Antonelli, Brynmor Haskell
The stability conditions of a relativistic hydrodynamic theory can be derived directly from the requirement that the entropy should be maximised in equilibrium. Here we use a simpl…
Gravitational waves from isolated neutron stars
Brynmor Haskell, Kai Schwenzer
Neutron star interiors are a fantastic laboratory for high density physics in extreme environments. Probing this system with standard electromagnetic observations is, however, a ch…
Multifluid Modelling of Relativistic Radiation Hydrodynamics
Lorenzo Gavassino, Marco Antonelli, Brynmor Haskell
The formulation of a universal theory for bulk viscosity and heat conduction represents a theoretical challenge for our understanding of relativistic fluid dynamics. Recently, it h…
