Hunting for intermediate-mass black holes in globular clusters: an astrometric study of NGC 6441
Maximilian Häberle, Mattia Libralato, Andrea Bellini +6
We present an astrometric study of the proper motions (PMs) in the core of the globular cluster NGC 6441. The core of this cluster has a high density and observations with current…
Prospects for Galactic and stellar astrophysics with asteroseismology of giant stars in the Continuous Viewing Zones and beyond
J. Ted Mackereth, Andrea Miglio, Yvonne Elsworth +30
The NASA- mission presents a treasure trove for understanding the stars it observes and the Milky Way, in which they reside. We present a first look at the prospects for…
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. XX. Ages of single and multiple stellar populations in seven bulge globular clusters
R. A. P. Oliveira, S. O. Souza, L. O. Kerber +23
In the present work we analyzed seven globular clusters selected from their location in the Galactic bulge and with metallicity values in the range $-1.30\lesssim\rm{[Fe/H]}\lesssi…
Astrometric and photometric study of NGC 6067, NGC 2506 and IC 4651 open clusters based on wide-field ground and Gaia DR2 data
Geeta Rangwal, R. K. S. Yadav, Alok Durgapal +2
We present an analysis of three southern open star clusters NGC 6067, NGC 2506 and IC 4651 using wide-field photometric and Gaia DR2 astrometric data. They are poorly studied clust…
The HST Large Programme on NGC 6752. I. Serendipitous discovery of a dwarf Galaxy in background
L. R. Bedin, M. Salaris, R. M. Rich +12
As part of a large Hubble Space Telescope investigation aiming at reaching the faintest stars in the Galactic globular cluster NGC 6752, an ACS/WFC field was the subject of deep op…
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters - XV. The dynamical clock: reading cluster dynamical evolution from the segregation level of blue straggler stars
F. R. Ferraro, B. Lanzoni, S. Raso +17
The parameter A+, defined as the area enclosed between the cumulative radial distribution of blue straggler stars (BSSs) and that of a reference population, is a powerful indicator…
