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…
