A family picture: tracing the dynamical path of the structural properties of multiple populations in globular clusters
E. Dalessandro, M. Cadelano, E. Vesperini +6
We studied the spatial distributions of multiple stellar populations (MPs) in a sample of 20 globular clusters (GCs) spanning a broad range of dynamical ages. The differences betwe…
Multiple Populations in Integrated Light Spectroscopy of Intermediate Age Clusters
Nate Bastian, Christopher Usher, Sebastian Kamann +9
The presence of star-to-star light-element abundance variations (a.k.a. multiple populations, MPs) appears to be ubiquitous within old and massive clusters in the Milky Way and all…
The search for multiple populations in Magellanic Clouds clusters - V. Correlation between cluster age and abundance spreads
S. Martocchia, E. Dalessandro, C. Lardo +14
In our HST photometric survey, we have been searching for multiple stellar populations (MPs) in Magellanic Clouds (MCs) massive star clusters which span a significant range of ages…
Spectroscopic detection of multiple populations in the ~2 Gyr old cluster Hodge 6 in the LMC
K. Hollyhead, S. Martocchia, C. Lardo +8
We report the spectroscopic discovery of abundance spreads (i.e. multiple populations) in the ~2 Gyr old cluster in the LMC, Hodge 6. We use low resolution VLT FORS2 spectra of 15…
Helium enrichment in intermediate-age Magellanic Clouds clusters: towards an ubiquity of multiple stellar populations?
W. Chantereau, M. Salaris, N. Bastian +1
Intermediate-age star clusters in the Magellanic Clouds harbour signatures of the multiple stellar populations long thought to be restricted to old globular clusters. We compare sy…
