The influence of small-scale magnetic field on the evolution of inclination angle and precession damping in the framework of 3-component model of neutron star [HEAP]

http://arxiv.org/abs/1708.07505


The evolution of inclination angle and precession damping of radio pulsars is considered. It is assumed that the neutron star consists of 3 “freely” rotating components: the crust and two core components, one of which contains pinned superfluid vortices. We suppose that each component rotates as a rigid body. Also the influence of the small-scale magnetic field on the star’s braking process is examined. Within the framework of this model the star simultaneously can have glitch-like events combined with long-period precession (with periods $10-10^{4}$ years). It is shown that the case of the small quantity of pinned superfluid vortices seems to be more consistent with observations.
