Abstract:
Vortex lines in the superfluid cores of neutron stars carry flux due to the induced proton charge current
which results from the Fermi liquid interaction between neutrons and protons. As a consequence the scattering
of charges off these magnetic vortex lines equilibrates the core superfluid to the plasma and the crust on
time scales of order 1 second after a glitch. Thus, the core superfluid cannot be responsible for the observe
time scales of the Vela and Crab pulsars. This result supports the theory of Alpar et al., in which both the
glitch and the slow postglitch relaxation are determined by the interaction of vortices with nuclei in
the crust.
