Age as a Major Factor in the Onset of Multiple Populations in Stellar Clusters
S. Martocchia, I. Cabrera-Ziri, C. Lardo +16
It is now well established that globular clusters (GCs) exhibit star-to-star light-element abundance variations (known as multiple stellar populations, MPs). Such chemical anomalie…
The Search for Multiple Populations in Magellanic Cloud Clusters III: No evidence for Multiple Populations in the SMC cluster NGC 419
S. Martocchia, N. Bastian, C. Usher +16
We present the third paper about our ongoing HST survey for the search for multiple stellar populations (MPs) within Magellanic Cloud clusters. We report here the analysis of NGC 4…
The chemical composition of the low-mass Galactic globular cluster NGC 6362
D. Massari, A. Mucciarelli, E. Dalessandro +6
We present chemical abundances for 17 elements in a sample of 11 red giant branch stars in NGC 6362 from UVES spectra. NGC 6362 is one of the least massive globulars where multiple…
