It has been recently argued that observations of the thermal emission from young neutron stars have the potential for constraining their structure and thence the underlying equation of state of dense matter. The thermal response of the crust of a neutron star to the rapid cooling of its core, however, depends critically on the superfluidity of matter in the crust. We here extended previous work on the specific heat of a nonuniform neutron superfluid in the inner crust of a neutron star by considering the possible presence of unusual nuclear shapes in its deeper layers and using a semiclassical model to determine the spatial behavior of the neutron pairing gap. We find that taking into account the existence of a lattice of nuclei (in both spherical and unusual shapes) in the sea of unbound neutrons increases significantly the diffusion times across the crust and thence the cooling times of the surface of the star, as compared to the standard scenario with a uniform neutron superfluid in the inner crust.
