The neutrino propagation in neutron stars is studied in the framework of the linear response method. The medium effects are treated in the nonrelativistic Brueckner-Hartree-Fock approach either in the mean-field approximation or in the random phase approximation. The residual interaction is expressed in terms of the Landau parameters extracted from the equation of state of spin- and isospin-polarized nuclear matter. The Brueckner theory including three-body forces is used for determining the equation of state. Numerical predictions for the response function of nuclear matter in β equilibrium and the neutrino mean free path are presented in a range of baryonic densities and temperatures. The main results are a dominance of the charge-exchange component over the scattering component and an enhancement of the neutrino mean free path induced by nuclear correlations.
