Chemical Evolution and Globular Clusters

9314911史密斯我们关于化学元素的起源、历史和分布的知识建立在恒星和星际气体中元素丰度的测量基础上。关键线索是在某些元素的丰度模式中找到的。将对球状星团中的恒星进行详细的重元素丰度分析。这为星系的早期化学演化和球状星团形成的时间尺度提供了至关重要的证据。

9314911 Smith Our knowledge of the origins, history and distribution of the chemical elements rests on measured elemental abundances in stars and interstellar gas. Key clues are found in the abundance patterns of certain elements. Detailed abundance analyses of the heavy elements will be carried out for stars in globular clusters. This yield crucial evidence on the early chemical evolution of the galaxy and the time scale for the formation of the globular clusters.
