Abstract EN
Glitches are sudden increases in the rotational frequency (ν) of a neutron star.
Glitches usually occur as fractional increase in the frequency of the order of ∆ν⁄ν =〖10〗^(-11)- 〖10〗^(-5).In this work we study the glitch in normal and magnetar pulsar stars, glitches are small or absent in the millisecond pulsar star because it is old star whereas the weak glitch activity of young pulsars by the fact that their internal temperatures are still too high for the crust to store a large stress .The results showed that NART (pulsed emission only at infrared) normal pulsar has more glitches than AXP (Anomalous X-ray Pulsar) and HE (Spin-powered pulsar with pulsed emission from radio to infrared or higher frequencies) stars, as the same time HE stars have more glitches than AXP, in a good agreement with the previous studies.
From the results can be conclude that study of neutron star glitches is a very important study in the evolution of neutron star as it helps in probing the neutron star interior.
