TL;DR
This paper reviews the evolution of massive stars in low-metallicity environments, emphasizing their role in chemical evolution and nucleosynthesis, and discusses observational constraints on early star generations.
Contribution
It provides a comprehensive overview of massive star evolution in low-Z environments and highlights key observational constraints on early stellar populations.
Findings
Massive stars significantly influence chemical evolution in dwarf galaxies.
Low-Z environments alter massive star evolution and nucleosynthesis pathways.
Observations can constrain models of the first stellar generations.
Abstract
Massive stars are the drivers of the chemical evolution of dwarf galaxies. We review here the basics of massive star evolution and the specificities of stellar evolution in low-Z environment. We discuss nucleosynthetic aspects and what observations could constrain our view on the first generations of stars.
