On the origin of UV-dim stars: a population of rapidly rotating shell stars?
Silvia Martocchia, Nate Bastian, Sara Saracino +1
The importance of stellar rotation in setting the observed properties of young star clusters has become clearer over the past decade, with rotation being identified as the main cau…
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 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…
