Confirmation of a metallicity spread amongst first population stars in globular clusters

HIGHLIGHTS

  • who: Lardo Carmela and colleagues from the Dipartimento di Fisica e Astronomia, Universitu00e1 degli Studi di Bologna, Via Gobetti, Bologna, Italy Astrophysics Research Institute, Liverpool John Moores University, Brownlow Hill, Liverpool , RF, UK have published the research work: Confirmation of a metallicity spread amongst first population stars in globular clusters, in the Journal: (JOURNAL)
  • what: In the following, the authors show how the authors can employ the F814W-(F275W-F814W) CMD of P1 stars to help discriminate between inhomogeneities in He and metallicity as the origin of the extended P1 phenomenon. This number of stars . . .
