The Search for Multiple Populations in Magellanic Cloud Clusters II: The Detection of Multiple Populations in Three Intermediate-Age SMC Clusters
F. Niederhofer, N. Bastian, V. Kozhurina-Platais +14
This is the second paper in our series about the search for multiple populations in Magellanic Cloud star clusters using the Hubble Space Telescope. Here we report the detection of…
A high fraction of Be stars in young massive clusters: evidence for a large population of near-critically rotating stars
N. Bastian, I. Cabrera-Ziri, F. Niederhofer +6
Recent photometric analysis of the colour-magnitude diagrams (CMDs) of young massive clusters (YMCs) have found evidence for splitting in the main sequence and extended main sequen…
The Search for Multiple Populations in Magellanic Cloud Clusters I: Two Stellar Populations in the Small Magellanic Cloud Globular Cluster NGC 121
F. Niederhofer, N. Bastian, V. Kozhurina-Platais +14
We started a photometric survey using the WFC3/UVIS instrument onboard the Hubble Space Telescope to search for multiple populations within Magellanic Cloud star clusters at variou…
Searching for GC-like abundance patterns in young massive clusters
I. Cabrera-Ziri, C. Lardo, B. Davies +4
Studies during the last decade have revealed that nearly all Globular Clusters (GCs) host multiple populations (MPs) of stars with a distinctive chemical patterns in light elements…
No evidence for younger stellar generations within the intermediate age massive clusters NGC 1783, NGC 1696 and NGC 411
I. Cabrera-Ziri, F. Niederhofer, N. Bastian +11
Recently, Li et al. (2016) claimed to have found evidence for multiple generations of stars in the intermediate age clusters NGC 1783, NGC 1696 and NGC 411 in the Large and Small M…
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…
Is the Escape Velocity in Star Clusters Linked to Extended Star Formation Histories? Using NGC 7252: W3 as a Test Case
I. Cabrera-Ziri, N. Bastian, M. Hilker +9
The colour-magnitude diagrams of some intermediate-age clusters (1-2 Gyr) star clusters show unexpectedly broad main-sequence turnoffs, raising the possibility that these clusters…
