Radiative heat transfer in surface layers of neutron stars with a magnetic field

Thermal conductivity due to Thomson scattering and free-free absorption of photons is numerically evaluated for a non-relativistic non-degenerate plasma in a magnetic field for a number of values ofb =ħωB/kT ⩾ 1000. In the case of pure scattering, simple fitting formulae are derived. Atb≫6, the magnetic field is shown to decrease (by about one order) the characteristic densities above which heat transfer is mainly determined by free-free transitions.
