Abstract

The coagulation theory of massive star formation predicts that the most massive stars form in the central densest part of a proto-cluster by stellar collisions and tidal mergers. A further prediction is a high frequency of tight binary systems among massive stars due to tidal capture and the combination of tidal disruption followed by a star-disc encounter (failed stellar mergers). Recent new observations have indeed confirmed this prediction (many short-period SB2 systems among O-stars in young clusters!).
