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).…

Spatial mixing of stellar populations in globular clusters via binary-single star scattering

Václav Pavlík, Melvyn B. Davies, Ellen I. Leitinger +5

The majority of Galactic globular star clusters (GCs) have been reported to contain at least two populations of stars (we use P1 for the primordial and P2 for the chemically-enrich…

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…

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…

Insights into spatial mixing of multiple populations in dynamically-young globular clusters

Václav Pavlík, Melvyn B. Davies, Ellen I. Leitinger +5

Many galactic globular clusters (GCs) contain at least two stellar populations. Recent observational studies found that the radial distributions of the first (P1) and second popula…

RR Lyrae Stars in Intermediate-age Magellanic Clusters: Membership Probabilities and Delay Time Distribution

Bolivia Cuevas-Otahola, Cecilia Mateu, Ivan Cabrera-Ziri +4

Recent works have challenged our canonical view of RR Lyrae (RRL) stars as tracers of exclusively old populations (~Gyr) by proposing a fraction of these stars to be of…
