Transport properties of dense matter. II

Exact solutions for the transport coefficients of a multicomponent system of several interacting Fermi liquids are given in the low temperature limit. The transport coefficients are found by solving a set of coupled Boltzmann transport equations. These solutions for the transport cofficients are used to evaluate the thermal conductivity and viscosity of neutron star matter in the density regime where neutron, proton, and electron liquids coexist. We give results for all the Fermi liquids in the normal state and indicate the changes that would occur for superfluid components. We find that the neutrons and electrons give similar size contributions and dominate the protons in determining the thermal conductivity. The shear viscosity is, however, determined almost completely by the neutrons if they are not superfluid. This work extends the previous work on the transport properties of dense matter by the present authors
