Planetesimals and larger bodies are traditionally thought to have formed via a hierarchical accretion, the formation of large objects via the collision and mergers of small objects. This process begins with the collision of dust due to Brownian motion producing larger aggregates held together by van der Waals forces. The aggregates settle toward the mid-plane of the disk and collide due to gas turbulence forming pebbles and larger objects. Further collisions and merger… WebHowever, young stellar systems often comprise more than two stars, which are expected to be in hierarchical configurations.

To be accreted, the gas particle has to be gravitationally bound to the sink and its angular momentum has to be sufficiently low.
