星团的诞生、演化和消亡
Birth, evolution and death of stellar clusters
摘要:
利用我们最近对星团物理学的更好理解,我们现在可以回答当代天体物理学中的一些基本问题。星团物理学直接关系到恒星初始质量函数的物理基础--任何O型恒星都是孤立形成的吗?随机恒星形成与竞争性吸积的相对重要性是什么?- 最大质量星系团的形成--不同类型的星系团质量函数是否不同?最大质量的星团是如何以及为什么在小的矮星系中形成的,这对更大的星团样本的积累意味着什么?人们可以(或应该)使用哪些主要的观测数据来尝试区分不同的恒星和星团形成场景?新出现的理论见解、新颖的高质量观测数据和下一代观测设施的出现,为这一领域关键的未决问题提供了令人满意和可靠的答案。
英文摘要:
Using our recently improved understanding of star cluster physics, we are now within reach of answering a number of fundamental questions in contemporary astrophysics. Star cluster physics has immediate bearing on questions ranging from the physical basis of the stellar initial mass function - Do any O-type stars form in isolation? What is the relative importance of stochastic (random) star formation versus competitive accretion? - to the build-up of the most massive clusters - Does the cluster mass function differ in different types of galaxies? How and why do the most massive star clusters form in small dwarf galaxies and what does that imply for the build-up of larger cluster samples? What are the main observables one could (or should) use to try and distinguish among the various star- and cluster-formation scenarios? Newly emerging theoretical insights, novel high-quality observational data and the advent of the next generation of observational facilities offer significant promise to reach satisfactory and robust answers to the key outstanding questions in this field.
