Multiple stellar populations and their evolution in globular clusters: A nucleosynthesis perspective

TL;DR

This review explores the characteristics and origins of multiple stellar populations in globular clusters, focusing on nucleosynthesis processes, discussing current theories, and highlighting open research questions.

Contribution

It provides a comprehensive synthesis of observational data and theoretical models related to multiple stellar populations in globular clusters from a nucleosynthesis perspective.

Findings

Multiple stellar populations exhibit distinct chemical signatures.

Current models face challenges explaining the origin of these populations.

Open questions remain about the formation and evolution mechanisms.

Abstract

This paper presents a review of the characteristics of the multiple stellar populations observed in globular clusters, and of their possible origin. The current theoretical issues and the many open questions are discussed.
