Outliers: multicolour photometry guiding the search for evolved binary systems in the globular cluster 47 Tucanae
Fabiola Campos, I. Pelisoli, S. Kamann +11
We use Hubble Space Telescope multicolour photometry of the globular cluster 47 Tucanae to uncover a population of 24 objects with no previous classification that are outliers from…
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters - XVII. Public Catalogue Release
D. Nardiello, M. Libralato, G. Piotto +13
In this paper we present the astro-photometric catalogues of 56 globular clusters and one open cluster. Astrometry and photometry are mainly based on images collected within the "H…
The Minimum Mass of Rotating Main Sequence Stars and its Impact on the Nature of Extended Main Sequence Turnoffs in Intermediate-Age Star Clusters in the Magellanic Clouds
Paul Goudfrooij, Leo Girardi, Andrea Bellini +3
Extended main sequence turn-offs (eMSTOs) are a common feature in color-magnitude diagrams (CMDs) of young and intermediate-age star clusters in the Magellanic Clouds. The nature o…
Ensemble Properties of the White Dwarf Population of the Old, Solar Metallicity Open Star Cluster Messier 67
Kurtis A. Williams, Paul A. Canton, A. Bellini +4
White dwarfs are excellent forensic tools for studying end-of-life issues surrounding low- and intermediate-mass stars, and the old, solar-metallicity open star cluster Messier 67…
The internal rotation of globular clusters revealed by Gaia DR2
P. Bianchini, R. P. van der Marel, A. del Pino +5
Line-of-sight kinematic studies indicate that many Galactic globular clusters have a significant degree of internal rotation. However, three-dimensional kinematics from a combinati…
Hubble Space Telescope Proper motion (HSTPROMO) Catalogs of Galactic Globular Clusters. VI. Improved data reduction and internal-kinematic analysis of NGC 362
M. Libralato, A. Bellini, R. van der Marel +6
We present an improved data-reduction technique to obtain high-precision proper motions (PMs) of globular clusters using Hubble Space Telescope data. The new reduction is superior…
HST astrometry in the 30 Doradus region: II. Runaway stars from new proper motions in the Large Magellanic Cloud
I. Platais, D. J. Lennon, R. P. van der Marel +12
We present a catalog of relative proper motions for 368,787 stars in the 30 Doradus region of the Large Magellanic Cloud (LMC), based on a dedicated two-epoch survey with the Hubbl…
Absolute HST Proper Motion (HSTPROMO) of Distant Milky Way Globular Clusters: Galactocentric Space Velocities and the Milky Way Mass
Sangmo Tony Sohn, Laura L. Watkins, Mark A. Fardal +4
We present Hubble Space Telescope (HST) absolute proper motion (PM) measurements for 20 globular clusters (GCs) in the Milky Way (MW) halo at Galactocentric distances $R_{\rm GC} \…
White Paper: Exoplanetary Microlensing from the Ground in the 2020s
Jennifer C. Yee, Jay Anderson, Rachel Akeson +25
Microlensing can access planet populations that no other method can probe: cold wide-orbit planets beyond the snow line, planets in both the Galactic bulge and disk, and free float…
The HST large programme on Centauri - II. internal kinematics
A. Bellini, M. Libralato, L. R. Bedin +7
In this second installment of the series, we look at the internal kinematics of the multiple stellar populations of the globular cluster Centauri in one of the parallel Hubble…
The HST large programme on Centauri -- III. Absolute proper motion
M. Libralato, A. Bellini, L. R. Bedin +11
In this paper we report a new estimate of the absolute proper motion (PM) of the globular cluster NGC 5139 ( Cen) as part of the HST large program GO-14118+14662. We analyzed a…
