dc.description.abstractSome pulsars are stable in the universe, even though, many of them glitch i.e. their spin frequencies increase suddenly. Young pulsars, such as the crab pulsar glitch within short period of time i.e. they glitch within a few years. However, old pulsars do not glitch as such. This thesis tries to analyze the causes behind these glitches and why their frequencies decrease with the ages of pulsars. We study the gravitational tidal force interaction between the core and the crust and employs its e ect on the long term evolution of pulsar glitches. In particular, we have shown that old pulsars show less glitches proportional to their ages and also we derived the time at which the crust and the core of neutron star will be tidally locked. Key Words: star: neutron star, pulsars: general, glitch: pulsar , tidal interactionen_US
