On the use of field RR Lyrae as Galactic probes: I. The Oosterhoff dichotomy based on fundamental variables
M. Fabrizio, G. Bono, V. F. Braga +21
We collected a large data set of field RR Lyrae stars (RRLs) by using catalogues already available in the literature and Gaia DR2. We estimated the iron abundances for a sub-sample…
Mapping the stellar age of the Milky Way bulge with the VVV. II. Deep JKs catalogs release based on PSF photometry
F. Surot, E. Valenti, S. L. Hidalgo +6
The bulge represents the best compromise between old and massive Galactic component, and as such its study is a valuable opportunity to understand how the bulk of the Milky Way for…
Analysis of the physical nature of 22 New VVV Survey Globular Cluster candidates in the Milky Way Bulge
Tali Palma, Dante Minniti, Javier Alonso-García +11
In order to characterize 22 new globular cluster (GC) candidates in the Galactic bulge, we present their colour-magnitude diagrams (CMDs) and Ks-band luminosity functions (LFs) usi…
Globular cluster candidates in the Galactic bulge: Gaia and VVV view of the latest discoveries
F. Gran, M. Zoccali, R. Contreras Ramos +7
Thanks to the recent wide-area photometric surveys, the number of star cluster candidates have risen exponentially in the last few years. Most detections, however, are based only o…
Mapping the stellar age of the Milky Way bulge with the VVV. I. The method
F. Surot, E. Valenti, S. L. Hidalgo +8
Recent observational programmes are providing a global view of the Milky Way bulge that serves as template for detailed comparison with models and extragalactic bulges. A number of…
