    "abstract": "The problem of wave disturbance propagation in rarefied gas in gravity field\nis explored. The system of hydrodynamic-type equations for a stratified gas in\ngravity field is derived from BGK equation by method of piecewise continuous\npartition function. The obtained system of the equations generalizes the\nNavier-Stokes at arbitrary density (Knudsen numbers). The verification of the\nmodel is made for a limiting case of a homogeneous medium. Results are in the\ngood agreement with experiment and former theories at arbitrary Knudsen\nnumbers.",
