Leveraging HST with MUSE: II. Na-abundance variations in intermediate age star clusters

S. Martocchia, S. Kamann, S. Saracino +13

Ancient (10 Gyr) globular clusters (GCs) show chemical abundance variations in the form of patterns among certain elements, e.g. N correlates with Na and anti-correlates with O.…

Leveraging HST with MUSE: I. Sodium abundance variations within the 2 Gyr-old cluster NGC 1978

S. Saracino, S. Kamann, C. Usher +10

Nearly all of the well studied ancient globular clusters (GCs), in the Milky Way and in nearby galaxies, show star-to-star variations in specific elements (e.g., He, C, N, O, Na, A…

Is Fornax 4 the nuclear star cluster of the Fornax dwarf spheroidal galaxy?

S. Martocchia, E. Dalessandro, M. Salaris +2

Fornax 4 is the most distinctive globular cluster in the Fornax dwarf spheroidal. Located close to the centre of the galaxy, more metal-rich and potentially younger than its four c…

Searching for globular cluster chemical anomalies on the main sequence of a young massive cluster

I. Cabrera-Ziri, J. S. Speagle, E. Dalessandro +9

The spectroscopic and photometric signals of the star-to-star abundance variations found in globular clusters seem to be correlated with global parameters like the cluster's metall…

Searching for Multiple Populations in the Integrated Light of the Young and Extremely Massive Clusters in the Merger Remnant NGC~7252

Nate Bastian, Carmela Lardo, Christopher Usher +8

Recent work has shown that the properties of multiple populations within massive stellar clusters (i.e., in the extent of their abundance variations as well as the fraction of star…

Chromosome maps of young LMC clusters: An additional case of coeval multiple populations

S. Saracino, S. Martocchia, N. Bastian +9

Recent studies have revealed that the Multiple Populations (MPs) phenomenon does not occur only in ancient and massive Galactic globular clusters (GCs), but it is also observed in…

Photometric characterization of multiple populations in star clusters: The impact of the first dredge-up

Maurizio Salaris, Chris Usher, Silvia Martocchia +6

The existence of star-to-star light-element abundance variations (multiple populations, MPs) in massive Galactic and extragalactic star clusters older than about 2 Gyr is by now we…

How stellar rotation shapes the colour magnitude diagram of the massive intermediate-age star cluster NGC 1846

Sebastian Kamann, Nate Bastian, Seth Gossage +19

We present a detailed study of stellar rotation in the massive 1.5 Gyr old cluster NGC 1846 in the Large Magellanic Cloud. Similar to other clusters at this age, NGC 1846 shows an…
