致密大质量星团的核心塌陷是不可避免的，这会导致质量高达1000 M☉甚至更大的大质量天体的形成。当这些物体成为恒星时，恒星风质量损失决定了它们的演化和最终命运，并决定它们是否形成黑洞（具有正常质量或中等质量）或爆炸为不稳定对超新星。在本文中，我们讨论了超大质量恒星的演化，并提出了一种方便的演化方案，可以在引力 N 体代码中实现，以研究致密大质量星团的动力学。
Core collapse of dense massive star clusters is unavoidable, and this leads to the formation of massive objects, with masses of up to 1000 M☉ and even larger. When these objects become stars, stellar wind mass loss determines their evolution and final fate, and decides on whether they form black holes (with normal mass or with intermediate mass) or explode as a pair-instability supernova. In this paper we discuss the evolution of very massive stars and present a convenient evolution recipe that can be implemented in a gravitational N-body code to study the dynamics of dense massive clusters.
