Stellar coalescence is suggested as a possible mechanism for doubling the upper stellar mass limit from ∼100M to ∼200M in a moderately dense cluster of a few hundred young massive stars (∼105 M pc−3). The merger will be between the two components of the dominant central tight binary formed in the core of the cluster by the N-body evolution. This process may occur in some giant extragalactic HII regions.
