Magnetic Field Decay In Cooling Neutron Stars
Abstract
We have carried out calculations of the Ohmic decay of dipolar magnetic fields which axe created so that they are initially confined to the crust. The effects of the evolution of the neutron stars, which have not been previously taken into account, are included. The results confirm the earlier work of Sang and Chanmugam (1987) that the field does not decay exponentially as generally assumed, and that if it occupies the entire crust it decays by less than a factor of order 100 in the Hubble time. Fields may decay more quickly if they are confined to the outer crust, but again non-exponentially in conflict with observations.
