| dc.description.abstract | Now a days there is no clear understanding of how pulsar's magnetic _eld decays. This is the motivation behind the development of this particular model for pulsar _eld dissipation. The work will be based on previous work in which it was shown that spinning polarization charges are the most likely sources of Neutron Star (NS) magnetic _eld. These _elds were indicated to be internal temperature dependent. Therefore, they are expected to decay as a result of cooling the NS interior. The present model for _eld decay is strongly linked to the long term (1-10 billion) yrs cooling of the NS core due to neutrino and photon emissions. Magnetic decay laws are formulated corresponding to each of the neutrino and photon branches of a standard NS cooling curve. So that this thesis work intends to show the decay of pulsar magnetic _eld due to photon emission. There after, magnetic _eld decays as a result of photon emission will be prominent for about 10 billion yrs. We will derive the magnetic _eld decay law and investigate how this law could be consistant with observations. | en_US |
