年轻的大质量星系团(YMC)是年轻恒星的密集集合体，它们构成了星系的基本构件。在银河系和本星系群中有几个例子，但它们在恒星爆发和相互作用的星系中尤其丰富。对于研究恒星质量函数以及恒星演化和恒星动力学之间的生态相互作用，少数几个足够接近的YMC是最有兴趣的。远距离未分辨星团可以有效地用于研究星团质量函数，并且对年轻星团群体的形成机制提供了很好的约束。预计YMC将成为许多不寻常天体的托儿所，包括广泛的奇异恒星和双星。到目前为止，在YMC中只发现了几个这样的天体，尽管它们的表亲球状星团异常地富含恒星外星体。在这篇综述中，我们重点讨论了∼100Myr之前的星团，比现在更老的几个星团，以及M。
Young massive clusters (YMCs) are dense aggregates of young stars that form the fundamental building blocks of galaxies. Several examples exist in the Milky Way Galaxy and the Local Group, but they are particularly abundant in starburst and interacting galaxies. The few YMCs that are close enough to resolve are of prime interest for studying the stellar mass function and the ecological interplay between stellar evolution and stellar dynamics. The distant unresolved clusters may be effectively used to study the star-cluster mass function, and they provide excellent constraints on the formation mechanisms of young cluster populations. YMCs are expected to be the nurseries for many unusual objects, including a wide range of exotic stars and binaries. So far only a few such objects have been found in YMCs, although their older cousins, the globular clusters, are unusually rich in stellar exotica. In this review, we focus on star clusters younger than ∼100 Myr, more than a few current crossing times old, and m...
