Scientific paper

Spin-down of the neutron superfluid in a pulsar is determined by the Magnus force and by the resistive force acting on the superfluid vortices. The temperature-independent component of the resistive force has been calculated previously. This paper contains an order of magnitude estimation of the temperature-dependent component produced by the interaction of thermally excited vortex core quasi-particles with neutron-drip lattice nuclei. The calculation provides a basis for relating period derivative relaxation, following a period discontinuity, with internal temperature.
