Magnetohydrodynamics in Superconducting-Superfluid Neutron Stars
MHD equations are presented for the mixture of superfluid neutrons, superconducting protons, and normal electrons believed to exist in the outer cores of neutron stars. The dissipative effects of electron viscosity and mutual friction due to electron-vortex scattering are also included. It is shown that Alfvén waves are replaced by cyclotronvortex waves that have not been previously derived fro...
متن کاملSuperfluid 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 کاملSuperconducting Superfluids in Neutron Stars
For treatment of the layers below the crust of a neutron star it is useful to employ a relativistic model involving three independently moving constituents, representing superfluid neutrons, superfluid protons, and degenerate negatively charged leptons. A Kalb Ramond type formulation is used here to develop such a model for the specific purpose of application at the semi macroscopic level chara...
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 ...
