Abstract

Recent studies have claimed the existence of very massive stars (VMS) up to 300 M in the local Universe. As this finding may represent a paradigm shift for the canonical stellar upper-mass limit of 150 M, it is timely to discuss the status of the data, as well as the far-reaching implications of such objects. We held a Joint Discussion at the General Assembly in Beijing to discuss (i) the determination of the current masses of the most massive stars, (ii) the formation of VMS, (iii) their mass loss, and (iv) their evolution and final fate. The prime aim was to reach broad consensus between observers and theorists on how to identify and quantify the dominant physical processes.
