These observations challenge the notion that star clusters are simple stellar populations, and pose serious questions regarding the mechanisms responsible for star cluster formation. In this project, we propose to collect WFC3 imaging that should lead to an understanding of the nature of the MMSTO phenomenon. We will perform deep F475W and F814W imaging for a complete sample of star clusters covering well-defined intervals of age and total mass. The sample comprises star clusters spanning a wide variety of concentrations and locations within the LMC and SMC, so as to allow a study of the physical properties causing the MMSTO phenomenon. The data will allow us to derive detailed star formation histories via CMD reconstruction methods, and locate the targets in the robust absolute age scale provided by clusters with dual red clumps. The underlying field population will be characterized by means of ACS images of nearby areas obtained in parallel. For all sample clusters more massive than 10^5 solar masses (including those with previous ACS/WFC imaging) we will also obtain high-S/N F336W imaging to probe star-to-star abundance variations in C and N along the RGB. Such variations are expected from self-enrichment from intermediate-mass stars within the clusters, in analogy with what is observed in the most massive old globular clusters. Thanks to its photometric depth and accuracy, the resulting dataset will constitute an invaluable resource for studies of stellar evolution and dynamics in star clusters.
The target star clusters which do NOT have archival ACS/WFC imaging available are observed with WFC3 using the F336W, F475W, and F814W filters. The target star clusters that DO have archival F555W and F814W ACS/WFC imaging available are observed with WFC3 using the F336W filter plus short exposures in F555W. We will thus yield images with three filters for each target star cluster, which will improve the age estimate (relative to the use of only two filters). Since the shape and position of the RGB is used to determine metallicities, we include exposures in each filter that do not saturate the bright giants. On the other hand, we need color uncertainties less than 0.05 mag down to well beyond the estimated magnitude of the main sequence turnoff to achieve an accurate age determination and to enable a robust identification of multiple turnoff structures in clusters with multiple stellar populations. Hence, at least one short exposure is used in each filter to avoid saturation of the giants and red clump stars, while at least two longer exposures are used to achieve deep photometry. At least two dither positions are used for each target star cluster to allow a robust elimination of hot pixels and cosmic ray hits during the analysis.
