Corequake Model of Pulsar Glitches for Neutron Stars with Pion-Condensed Core

Abstract

From the viewpoint that combined (charged plus neutral) pion condensates come into playin the core of massive 1.4 -1.6)Mo ) neutron stars, a possible explanation for the remarkable difference in glitches of Vela and Crab pulsars is given by applying a new version of corequake model to Vela glitches.
