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…
A Young Cluster With an Extended Main Sequence Turnoff: Confirmation of a Prediction of the Stellar Rotation Scenario
N. Bastian, F. Niederhofer, V. Kozhurina-Platais +13
We present Hubble Space Telescope photometry of NGC1850, a ~100 Myr, ~10^5 Msun cluster in the Large Magellanic Cloud. The colour magnitude diagram clearly shows the presence of an…
Near-Infrared Observations of Globular Clusters in NGC 4472, NGC 4594, NGC 3585 and NGC 5813 and Implications for their Ages and Metallicities
Maren Hempel, Steve Zepf, Arunav Kundu +2
We present near-infrared photometry of the globular cluster systems of the early-type galaxies NGC 4472, NGC 4594, NGC 3585, and NGC 5813. We combine these near-infrared data, obta…
The intermediate-age open clusters Ruprecht 61, Czernik 32, NGC 2225 and NGC 2262
G. Carraro, G. Baume, R. Vazquez +2
We present the first CCD photometry to of 4 fields centered on the region of the southern Galactic star clusters Ruprecht~61, Czernik~32, NGC 2225 and NGC 2262 and o…
