Hubble Space Telescope proper motions of Large Magellanic Cloud star clusters -- II. Kinematic structure of young and intermediate-age clusters
F. Niederhofer, L. Cullinane, D. Massari +14
In this paper, we explore the kinematic properties of a sample of 19 young (<1 Gyr) and intermediate-age (1-2.5 Gyr) massive star clusters within the Large Magellanic Cloud (LMC).…
Serendipitous Discovery of a Faint Planetary Nebula in the Massive Young LMC Cluster NGC 1866
Howard E. Bond, Nate Bastian, Andrea Bellini +5
During an integral-field spectroscopic study of stars in the massive young open cluster NGC 1866 in the Large Magellanic Cloud, we serendipitously discovered a faint planetary nebu…
Characterizing the star cluster populations in Stephan's Quintet using HST and JWST observations
P. Aromal, S. C. Gallagher, K. Fedotov +14
Stephan's Quintet (SQ) is a local compact galaxy group system that exhibits significant star formation activity. A history of tidal interactions between its four member galaxies an…
Cluster Ages to Reconstruct the Milky Way Assembly (CARMA) IV. Chrono-dynamics of seven old star clusters in the Large Magellanic Cloud and the peculiar origin of NGC 1841
F. Niederhofer, D. Massari, F. Aguado-Agelet +15
In this study, we report conclusive evidence for an ancient star cluster that has been accreted by the Large Magellanic Cloud (LMC). By leveraging observations from the Hubble Spac…
Testing the Role of Merging Binaries in the Formation of the Split Main Sequence in Young Clusters
Nate Bastian, Sebastian Kamann, Florian Niederhofer +1
A number of theories have been put forward to explain the bi-modal stellar rotational distribution observed in young massive clusters. These include stellar mergers and interaction…
Tracing stellar rotation in young massive LMC clusters
Sebastian Kamann, Nate Bastian, Florian Niederhofer +8
We present a detailed analysis of stellar rotation along the main sequences of NGC 1866 and NGC 1856, two young (~200-300 Myr) massive clusters in the Large Magellanic Cloud, using…
The Yasone catalogue: three new Milky Way satellites and 17 further hypercompact candidates
J. Untzaga, M. Mezcua, S. Bonoli +5
We present the discovery of three new low-latitude (|b| ~ 20) Milky Way satellites: Yasone-1, Yasone-2, and Yasone-3. They were identified in our search for compact stell…
Stellar rotation in the intermediate-age massive cluster NGC 1783: clues on the nature of UV-dim stars
Silvia Leanza, Emanuele Dalessandro, Mario Cadelano +9
Over the past decade, stellar rotation has emerged as a key factor in shaping the morphology of color-magnitude diagrams of young and intermediate-age star clusters. In this study,…
Massive Star Clusters in the Semi-Analytical Galaxy Formation Model L-Galaxies 2020
Nils Hoyer, Silvia Bonoli, Nate Bastian +7
It is established that there exists a direct link between the formation history of star cluster populations and their host galaxies. However, our lack of understanding of the assem…
