Contribution Of Gravitational And Magnetic Dipole Radiations To The Ellipticity Of Pulsars

Accurate and reliable calculation of the ellipticity parameter is very important inrnorder to theoretically study the gravitational waves emitted by pulsars which is a hotrnresearch area in the field astrophysics. Ellipticity is a result of lack in symmetry ofrnspherical bodies. In the case of pulsars rotation and magnetic fields are the causesrnof deformation. According to relativistic plasma diffusion model for neutron starrnmagnetic fields, the surface magnetic field of neutron stars depends on their rotationrnfrequency. Hence it can be deduced that the parameter ellipticity depends on thernrotational frequency.rnBut gravitational and magnetic dipole radiations affect the rotational frequency ofrnpulsars which in turn will also affect the parameter ellipticity. In this work we willrnestimate the contributions of gravitational and dipole radiations to the parameterrnellipticity
