The importance of taking the collective effects of the nucleon medium into account in the problem of neutron star luminosity is demonstrated. The following processes are introduced: (1) nonresonant processes which, while reducible to two-nucleon reactions, take multiple scattering in intermediate states into consideration; and (2) resonant processes related to the collective vibrations of the medium (i.e. spin sound and pion condensate). The contributions made by the most significant processes to luminosity are calculated and it is shown that the resulting luminosity is strongly dependent upon the mean density of nuclear matter; as the mean density increases, the luminosity greatly exceeds values obtained in previous calculations in which collective effects were not taken into account. Hence, the greater the mean density of the neutron star, the faster is the rate at which neutrinos are emitted. The neutrino mean free paths in various direct processes are calculated.
