Chemical evolution in star clusters: the role of mass and environment    [PDF]

The process of chemical self-enrichment in stellar systems can be affected by the total mass of the system and the conditions of the large-scale environment. Globular clusters are a special dark matter-free case of chemical evolution, in which the only self-enrichment comes from material processed in stars, and only two bursts of star formation occur. We describe how observations of intermediate-age star clusters in the Large Magellanic Cloud can provide insight on the ways that mass and environment can affect the process of chemical enrichment in star clusters.
