Scientific paper

Massive stars are typically found in the centers of young, dense clusters. Encounters between massive protostars and their less-massive cluster siblings are frequent enough to impact their formation processes. We present the results of numerical studies concerning the interaction of a massive-star disk system and an impacting star, which suggest that disk-assisted capture can contribute significantly to the high multiplicity of massive stars. We discuss the results of N-body simulations of this process, as well as the observational clues that point to this scenario. A potential example of a capture process in Cepheus A is presented along with modeling of this system.
