Abstract: In this poster, we discuss the dynamical behavior of gas ̊owing around a core of mass Mc = 10MEarth that is embedded in a near Keplerian background flow. We find that the flow is characterized by a strong 'flip-flop' behavior and no static envelope forms. Over the course of the simulation the amount of mass surrounding the core is roughly constant, but the varying flow pattern gives rise to regular and large 'eruptions' of matter from the region around the core which return matter to the background flow: mass in the envelope at one time is not found in the envelope at any later time.
