Abstract

The motion of the neutron-proton vortex system in neutron stars is examined taking pinning and depinning of the vortices into account. The relaxation solution of the equations for the dynamics of pulsar rotation after glitches is compared with observational data on the Vela pulsar. It is shown that the angular rotation relaxation parameters are related both to the appearance of a “density wave” of neutron vortices during a glitch and to features of the motion of the vortices between successive glitches.
