A closer look at the binary content of NGC 1850
S. Saracino, S. Kamann, N. Bastian +7
Studies of young clusters have shown that a large fraction of O-/early B-type stars are in binary systems, where the binary fraction increases with mass. These massive stars are pr…
Exploring the role of binarity in the origin of the bimodal rotational velocity distribution in stellar clusters
S. Kamann, N. Bastian, C. Usher +2
Many young and intermediate age massive stellar clusters host bimodal distributions in the rotation rates of their stellar populations, with a dominant peak of rapidly rotating sta…
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…
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…
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…
