摘要 最近的研究表明，在本地宇宙中存在高达 300 M⊙ 的超大质量恒星 (VMS)。由于这一发现可能代表了标准恒星质量上限 150 M⊙ 的范式转变，因此现在是讨论数据状态以及此类物体的深远影响的时候了。我们在北京举行的大会上举行了一次联合讨论，讨论了（i）最大质量恒星当前质量的确定，（ii）VMS的形成，（iii）它们的质量损失，以及（iv）它们的演化和最终命运。主要目的是在观察者和理论家之间就如何识别和量化主要物理过程达成广泛共识。
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.
