Inverse weak relationship between glitch rate and characteristic age

Correlation analysis using Pearson's coefficient

Abstract

An updated analysis of pulsar glitch parameters was conducted using a sample of 215 pulsars, encompassing 677 recorded glitch events, each glitch at least once between 1968 and 2024. The glitch rates were estimated and plotted against various pulsar parameters, including rotational frequency, spin-down rate, and characteristic age. These relationships were analyzed using Pearson's correlation coefficient. The results indicate linear and weak relationships between glitch rate and the pulsar parameters. However, the relationship between glitch rate and characteristic age is inversely weak.
