Abstract


The "pasta" regime in neutron star matter (NSM) stands for a complex "topological" transition occurring at sub-saturation densities and temperatures around 1-2MeV. These changes are supposed to influence the thermal relaxation across the "inner crust" of neutron stars. Thus, the thermal conductivity response throughout the "pasta" breakdown appears as a relevant issue in the star cooling process (caused by neutrino emissions). We studied the thermal conductivity within the context of nuclear potentials, embedded in an effective (i.e. Thomas-Fermi) Coulomb potential. No only a dramatic change of the nucleons thermal conductivity could be observed around T=1 MeV, but also a decoupling between the conductivities of protons and neutrons, as matter becomes increasingly asymmetric.
