Description
As theoretical calculations and recent simulations indicate, neutron stars must have a stronger toroidal field component in the outer core which surrounds the poloidal field. Then, this toroidal field in the form of flux lines will offer pinning sites for vortex lines similar to the conditions in the inner crust. As we have shown, the moment of inertia of the corresponding region can be larger than that of the crust depending on the radial extension of the toroidal flux. Furthermore, we found that the response of the toroidal flux line region to a glitch is exponential relaxation with timescales of the order of several days to months fitting the postglitch observations. Due to the contribution of toroidal flux region, angular momentum constraint for the glitches changes and our findings can resolve entrainment crisis for large glitches.
