Thermal conductivity of neutrons in neutron star cores [PDF]
Astronomy & Astrophysics, 2001 The diffusive thermal conductivity of neutrons in dense matter [$ρ\sim (1 - 8) \times 10^{14}$ g cm$^{-3}$] of neutron star cores is calculated. The contribution from neutron--neutron and neutron--proton collisions is taken into account. We use the transition probabilities calculated for symmetric dense nucleon matter on the basis of the Dirac ...
