SUMMARY:Nucleosynthesis at the isotopic level: how chemical abundances enh
 ance our understanding of globular clusters and dwarf galaxies - Madeleine
  McKenzie (Carnegie)

CONTACT:Sandro Tacchella
DESCRIPTION:In the context of hierarchical galaxy assembly\, both globular
  clusters and dwarf galaxies serve as indispensable probes of the formatio
 n of our Milky Way. The chemical composition of stars within these ancient
  structures plays a pivotal role in constraining their chemical enrichment
  history. To date\, most studies have focused almost exclusively on elemen
 tal abundances\, however\, nucleosynthesis operates at the isotopic level.
  This talk will discuss how Mg isotope ratios shed light on both the accre
 ted dwarf galaxy component of our Milky Way and the light element enhanced
  populations within globular clusters. This reveals contributions from sup
 ernova and low-mass stars that cannot be discerned through element abundan
 ces alone.
