Scientific paper
The authors compute the interaction of planetesimals with the envelopes of growing giant planets that form by the "core-instability" mechanism. According to this mechanism, a core grows by the accretion of solid bodies in the solar nebula, and the growing core becomes progressively more effective in gravitationally contracting gas from the surrounding solar nebula into an envelope, until a "runaway" accretion of gas occurs. The two-body trajectories of planetesimals through this envelope are computed. The implications for the formation of the giant planets by this sort of mechanism and its influence on their composition are discussed.
