Thermal conductivity κ as a function of mass density ρ in the inner crust and outer core of a neutron star for the nuclear energy density functionals BSk22, BSk24, BSk25, and BSk26. Vertical arrows mark the proton drip densities. Vertical dotted lines mark the crust-core interface. For the core densities, the electron (lower lines) and total (electron and baryon, upper lines) conductivities are shown. Inset:κ vs. ρ in the outer and inner crust for the model BSk24 (the ground state) compared with the accreted crust models F+18 and HZ’08. The dots on the curves mark the neutron drip for each model.
