Title: The Sparsest Clusters With O Stars Authors: J. B. Lamb, M. S. Oey, J. K. Werk, L. D. Ingleby There is much debate on how high-mass star formation varies with environment, and whether the sparsest star-forming environments are capable of forming massive stars. To address this issue, we have ob...
