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

TL;DR

This paper investigates how the mass of star clusters and their environmental conditions influence chemical self-enrichment processes, using observations of intermediate-age clusters in the Large Magellanic Cloud.

Contribution

It provides new insights into the effects of mass and environment on chemical evolution in star clusters, especially globular clusters, through observational analysis.

Findings

Mass and environment significantly impact chemical enrichment processes.

Globular clusters show self-enrichment from stellar processed material.

Observations of LMC clusters reveal environmental influences on chemical evolution.

Abstract

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.
