Spectrophotometry in the integrated light of multiple populations in globular clusters
Vinicius Branco, Ariane Lançon, Paula Coelho +7
There is vast evidence from observations of multiple stellar populations (MPs) in globular clusters (GCs). To explore the issue theoretically, this work considers two subsolar meta…
