No Evidence for Chemical Abundance Variations in the Intermediate-age Cluster NGC 1783
Hao Zhang, Richard de Grijs, Chengyuan Li +1
We have analyzed multi-passband photometric observations, obtained with the {\it Hubble Space Telescope}, of the massive (), intermediate-age (1.8 Gyr-old)…
Not-so-simple stellar populations in nearby, resolved massive star clusters
Richard de Grijs, Chengyuan Li
Around the turn of the last century, star clusters of all kinds were considered "simple" stellar populations. Over the past decade, this situation has changed dramatically. At the…
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 dynamical origin of multiple populations in intermediate-age clusters in the Magellanic Clouds
Jongsuk Hong, Richard de Grijs, Abbas Askar +7
Numerical simulations were carried out to study the origin of multiple stellar populations in the intermediate-age clusters NGC 411 and NGC 1806 in the Magellanic Clouds. We perfor…
Discovery of Extended Main Sequence Turn-offs in Four Young Massive Clusters in the Magellanic Clouds
Chengyuan Li, Richard de Grijs, Licai Deng +1
An increasing number of young massive clusters (YMCs) in the Magellanic Clouds have been found to exhibit bimodal or extended main sequences (MSs) in their color--magnitude diagram…
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…
