|dc.description.abstract||Accurate and reliable calculation of the ellipticity parameter is very important in order to theoretically study the gravitational waves emitted by pulsars which is a hot research area in the field astrophysics. Ellipticity is a result of lack in symmetry of spherical bodies. In the case of pulsars rotation and magnetic fields are the causes of deformation. According to relativistic plasma diffusion model for neutron star magnetic fields, the surface magnetic field of neutron stars depends on their rotation frequency. Hence it can be deduced that the parameter ellipticity depends on the rotational frequency. But gravitational and magnetic dipole radiations affect the rotational frequency of pulsars which in turn will also affect the parameter ellipticity. In this work we will estimate the contributions of gravitational and dipole radiations to the parameter ellipticity.||en_US|
