Disentangling the Complexity of Old Stellar Populations

星系形成是现代天文学中的一个突出问题。星团是宇宙的基本组成部分。最古老的恒星聚集体是球状星团，其恒星的组成模式在其他地方是找不到的。这个项目的目的是通过研究球状星团在许多不同环境中的组成恒星的组成，给球状星团带来新的理解。这幅图中的图案揭示了恒星形成的历史和球状星团本身的形成。这些反过来又参与了星系的形成。该项目旨在利用这些恒星来探测球状星团的形成和银河系的恒星成分，从而将这些古老的恒星与更大的宇宙学问题联系起来。

Galaxy formation is an outstanding problem in modern astronomy. Star clusters are the basic building blocks in the Universe. The oldest stellar aggregates are the globular clusters whose stars show patterns in composition that are not found elsewhere. This project aims to bring new understanding to globular clusters by studying the composition of their constituent stars in many different environments. Patterns in this composition reveal the history of star formation and the formation of the globular clusters themselves. These are in turn involved in the formation of galaxies. The project aims to use these stars to probe the formation of globular clusters and the stellar components of the Galaxy, and hence link these old stars to larger cosmological questions.
