On the Glitch Evolution of Pulsars

TL;DR

This paper models pulsar glitches to better understand neutron star interiors, explaining observed glitch behaviors across different pulsar types and ages, and accounting for the absence of glitches in the youngest and oldest pulsars.

Contribution

It introduces a model that explains the evolution of pulsar glitches across various neutron star manifestations, including specific pulsars and age groups.

Findings

Crab and Vela pulsar glitches are explained by the model.

The model accounts for the low glitch rate in very young and very old pulsars.

Observed glitch properties are linked to neutron star interior evolution.

Abstract

Observations of pulsar glitches remain a powerful tool for studying the interior of neutron stars. Many of the observed glitch properties are shown to result from the evolution of glitches in the different manifestations of neutron stars. Specifically, the type of glitches associated with the Crab and Vela pulsars are explained by this model. We are, also, able to adequately account for the absence, or very low rate, of glitches among the youngest and the very old pulsars.
