Pulsars Magnetic Field Decay Due To Photon Emissions

Now a days there is no clear understanding of how pulsar's magnetic _eld decays.rnThis is the motivation behind the development of this particular model for pulsar _eldrndissipation. The work will be based on previous work in which it was shown that spinningrnpolarization charges are the most likely sources of Neutron Star (NS) magnetic _eld.rnThese _elds were indicated to be internal temperature dependent. Therefore, they arernexpected to decay as a result of cooling the NS interior. The present model for _eldrndecay is strongly linked to the long term (1-10 billion) yrs cooling of the NS core duernto neutrino and photon emissions. Magnetic decay laws are formulated corresponding torneach of the neutrino and photon branches of a standard NS cooling curve. So that thisrnthesis work intends to show the decay of pulsar magnetic _eld due to photon emission.rnThere after, magnetic _eld decays as a result of photon emission will be prominent forrnabout 10 billion yrs. We will derive the magnetic _eld decay law and investigate how thisrnlaw could be consistant with observations.
