The gas dynamics of a disintegrating multicomponent vapor cloud in vacuum in the presence of gravity field is investigated in connection with the development of a shock vaporization model for the accretion stage of planet formation. It is shown that the vaporization of matter as a result of a high-velocity impact and the subsequent dispersion will result in a partial escape of vapor outside the growing planet if the combined gas-dynamical and thermal velocity of the atomic-molecular particles is higher than the escape velocity. The selective dissipation of the impact-generated cloud is one of the mechanisms of planetary matter differentiation at the accretion stage. The differentiation is brought about by the difference of the thermal velocities of vapor-cloud components of different masses during the transition from the expansion phase of the cloud to nonimpact regime.
