Implications of the Crustal Moment of Inertia for Neutron Star Equations of State

Abstract

The dynamical models for neutron star glitches and postglitch behaviour, and the information they yield on the crustal moment of inertia, are applied to a catalogue of neutron star models. The implications for neutron star equations of state are discussed. The postglitch timing data from the Vela pulsar are interpreted to rule out one of the softer equations of state for neutron matter with an admixture of hypersons, if the neutron star mass is 1.4 solar mass.
