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