Hubble Space Telescope Proper Motion (HSTPROMO) Catalogs of Galactic Globular Clusters. V. The rapid rotation of 47 Tuc traced and modeled in three dimensions
A. Bellini, P. Bianchini, A. L. Varri +5
High-precision proper motions of the globular cluster 47 Tuc have allowed us to measure for the first time the cluster rotation in the plane of the sky and the velocity anisotropy…
The State-of-the-Art HST Astro-Photometric Analysis of the core of ωCentauri. III. The Main Sequence's Multiple Populations Galore
A. Bellini, A. P. Milone, J. Anderson +5
We take advantage of the exquisite quality of the Hubble Space Telescope 26-filter astro-photometric catalog of the core of Omega Cen presented in the first paper of this series an…
The State-of-the-Art HST Astro-Photometric Analysis of the core of Centauri. II. Differential-Reddening Map
A. Bellini, J. Anderson, R. P. van der Marel +3
We take advantage of the exquisite quality of the Hubble Space Telescope astro-photometric catalog of the core of wCen presented in the first paper of this series to derive a high-…
The State-of-the-Art HST Astro-Photometric Analysis of the core of Centauri. I. The Catalog
A. Bellini, J. Anderson, L. R. Bedin +4
We have constructed the most-comprehensive catalog of photometry and proper motions ever assembled for a globular cluster (GC). The core of Cen has been imaged over 650 times th…
