Transport coefficients for multicomponent Fermi liquids at low temperatures are analytically derived. Coupled Boltzmann transport equations are solved to compute the thermal conductivity and viscosity of neutron‑star matter composed of neutrons, protons, and electrons. In the normal state, neutrons and electrons contribute similarly and dominate thermal conductivity, while shear viscosity is almost entirely determined by neutrons unless they become superfluid. Published in The Astrophysical Journal (June 1979), DOI 10.1086/157145, this study focuses on transport properties of dense matter in neutron stars.

Abstract 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 coefficients are used to evaluate the thermal conductivity and viscosity of neutron star matter in the density regime where neutron, proton, and electron liquids coexist. Results are given for all the Fermi liquids in the normal state and indicate the changes that would occur for superfluid components. It is found 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.
