Variable stars in two open clusters within the Kepler 2-Campaign-0 field: M 35 and NGC 2158
D. Nardiello, L. R. Bedin, V. Nascimbeni +15
We present a multi-year survey aimed at collecting (1) high-precision (~5 milli-mag), (2) fast-cadence (~3 min), and (3) relatively long duration (~10 days) multi-band photometric…
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. I. Overview of the Project and Detection of Multiple Stellar Populations
G. Piotto, A. P. Milone, L. R. Bedin +23
In this paper we describe a new UV-initiative HST project (GO-13297) that will complement the existing F606W and F814W database of the ACS Globular Cluster (GC) Treasury by imaging…
A bag of tricks: Using proper motions of Galactic stars to identify the Hercules ultra-faint dwarf galaxy members
M. Fabrizio, G. Raimondo, E. Brocato +13
Hercules is the prototype of the ultra-faint dwarf (UFD) galaxies. To date, there are still no firm constraints on its total luminosity, due to the difficulty of disentangling Herc…
M4 Core Project with HST - III. Search for variable stars in the primary field
V. Nascimbeni, L. R. Bedin, D. C. Heggie +14
We present the results of a photometric search for variable stars in the core of the Galactic globular cluster M4. The input data are a large and unprecedented set of deep Hubble S…
Ground-based astrometry with wide field imagers. V. Application to near-infrared detectors: HAWK-I@VLT/ESO
M. Libralato, A. Bellini, L. R. Bedin +5
High-precision astrometry requires accurate point-spread function modeling and accurate geometric-distortion corrections. This paper demonstrates that it is possible to achieve bot…
