Impact of internal heating on the thermal evolution of neutron stars.


Abstract (from CDS):

The impact of various competing heating processes on the thermal evolution of neutron stars is investigated. We show that internal heating leads to significantly enhanced surface temperatures for pulsars of middle and old age. The heating due to thermal creep of pinned vortices and due to outward motion of proton vortices in the interior of the star leads to a better agreement with the observed data in the case of enhanced cooling. The strong pinning models are ruled out by a comparison with the cooling data on the old pulsars. For millisecond pulsars, the heating due to thermal creep of pinned vortices and chemical heating of the core have the largest impact on the surface temperatures. The angular dependence of the heating rates require two dimensional cooling simulations in general. Such a simulation is performed for a selected case in order to check the applicability of one-dimensional codes used in the past.
