Magneto-thermal evolution of isolated neutron stars: towards the grand unification

Thanks to the last decades of X-ray observations, the picture of an apparently heterogeneous zoo of isolated neutron stars is emerging. In the attempt of unifying their different phenomenological classes, a key issue is the understanding of the cooling and spin-down history of the isolated neutron stars. I present the results of our recent 2D code in which the thermal evolution is coupled to the magnetic field evolution, including, for the first time, both Ohmic dissipation and Hall drift. Theoretical models, and their predictions, are then compared with observational data of about fourty isolated neutron stars, belonging to different observational classes, in which the thermal emission has been clearly detected.
