Description
An extended superfluid vortex line–magnetic flux tube interaction model is proposed for the magneto-thermal-rotational evolution of neutron stars. Applications to a sample of 12 radio pulsars with reliably measured braking indices demonstrate significantly improved agreement compared to the preexisting models. The effective moment of inertia change term for glitching pulsars is derived from vortex creep theory and connected to the directly observable glitch activity parameter, making the model fully predictive for the glitching sources as well.
This work paves the way for a fully self-consistent coupled magneto-thermal–rotational evolution model of neutron stars, incorporating the microphysical vortex pinning/creep framework, realistic core magnetic field configurations with various dissipation mechanisims, and modern neutron star cooling codes.
