Superfluid Neutron Stars
Neutrons stars are believed to contain in their interior superfluid neutrons and superconducting protons. This is suggested by nuclear physics calculations and by the very long relaxation time scales after ‘glitches’ (sudden increases of the neutron star angular velocity). Over the last years, we have been developing a formalism that can describe the relativistic hydrodynamics of mixtures of su...
متن کاملSuperfluid vortices in neutron stars
A microscopic, quantum mechanical model for neutron vortices in the crust of a neutron star is presented. After a brief introduction to the Bogoliubov-de Gennes equations, which form the basis for our calculations, we present results for density distributions, vortex core sizes and vortex energies, both for an isolated neutron vortex and for the case when the vortex core overlaps with a cylindr...
متن کاملModelling the dynamics of superfluid neutron stars
In this brief summary I describe our recent work on superfluid neutron star dynamics. I review results on shear viscosity, hyperon bulk viscosity, vortex mediated mutual friction and the modelling of multifluid systems in general. For each problem I provide a set of questions that need to be addressed by future work.
متن کاملMutual friction in superfluid neutron stars
We discuss vortex-mediated mutual friction in the two-fluid model for superfluid neutron star cores. Our discussion is based on the general formalism developed by Carter and collaborators, which makes due distinction between transport velocity and momentum for each fluid. This is essential for an implementation of the so-called entrainment effect, whereby the flow of one fluid imparts momentum ...
متن کاملr-modes in superfluid neutron stars
The analogues of r-modes in superfluid neutron stars are studied here. These modes, which are governed primarily by the Coriolis force, are identical to their ordinary-fluid counterparts at the lowest order in the small angular-velocity expansion used here. The equations that determine the next order terms are derived and solved numerically for fairly realistic superfluid neutron-star models. T...
