Query: 2D Cooling of Magnetized Neutron Stars   Context: Many thermally emitting isolated neutron stars have magnetic fields
larger than 10^13 G. A realistic cooling model that includes the presence of
high magnetic fields should be reconsidered. Aims: We investigate the effects
of anisotropic temperature distribution and Joule heating on the cooling of
magnetized neutron stars. Methods: The 2D heat transfer equation with
anisotropic thermal conductivity tensor and including all relevant neutrino
emission processes is solved for realistic models of the neutron star interior
and crust. Results: The presence of the magnetic field affects significantly
the thermal surface distribution and the cooling history during both, the early
neutrino cooling era and the late photon cooling era. Conclusions: There is a
large effect of the Joule heating on the thermal evolution of strongly
magnetized neutron stars. Both magnetic fields and Joule heating play a key
role in keeping magnetars warm for a long time. Moreover, this effect is
important for intermediate field neutron stars and should be considered in
radio-quiet isolated neutron stars or high magnetic field radio-pulsars.
