Discovery of astrometric accelerations by dark companions in the globular cluster Centauri

Imants Platais, Johannes Sahlmann, Leo Girardi +6

We present results from the search for astrometric accelerations of stars in Centauri using 13 years of regularly-scheduled {\it Hubble Space Telescope} WFC3/UVIS calibration o…

The effects of stellar rotation along the main sequence of the 100 Myr old massive cluster NGC 1850

Sebastian Kamann, Sara Saracino, Nate Bastian +13

Young star clusters enable us to study the effects of stellar rotation on an ensemble of stars of the same age and across a wide range in stellar mass and are therefore ideal targe…

Age and helium content of the open cluster NGC 6791 from multiple eclipsing binary members. III. Constraints from a subgiant

K. Brogaard, F. Grundahl, E. L. Sandquist +18

Models of stellar structure and evolution can be constrained using accurate measurements of the parameters of eclipsing binary members of open clusters. Multiple binary stars provi…

2D kinematics of massive stars near the Galactic Center

Mattia Libralato, Daniel J. Lennon, Andrea Bellini +12

The presence of massive stars (MSs) in the region close to the Galactic Center (GC) poses several questions about their origin. The harsh environment of the GC favors specific form…

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.…

HST astrometry in the Orion Nebula Cluster: census of low-mass runaways

Imants Platais, Massimo Robberto, Andrea Bellini +6

We present a catalog of high-precision proper motions in the Orion Nebula Cluster (ONC), based on Treasury Program observations with the Hubble Space Telescope's (HST) ACS/WFC came…
