On the Use of Field RR Lyrae as Galactic Probes -- VIII. Early Formation of the Galactic Spheroid
G. Bono, V. F. Braga, M. Fabrizio +54
We introduce a new photometric catalog of RR Lyrae variables (RRLs, 300,000) mainly based on data available in public datasets. We also present the largest and most homogeneo…
The dwarf irregular galaxy NGC 6822. II. Young, intermediate and old stellar populations: comparison between theory and observations
Maria Tantalo, Giuseppe Bono, Maurizio Salaris +14
This paper presents a quantitative analysis of the stellar content in the Local Group dwarf irregular galaxy NGC 6822 by comparing stellar evolution models and observations in colo…
Differential reddening in 48 globular clusters: An end to the quest for the intracluster medium
E. Pancino, A. Zocchi, M. Rainer +9
For decades, it has been theorized that a tenuous but detectable intracluster medium should be present in globular clusters, which is continuously replenished by the gas and dust e…
Weak Galactic Halo--Fornax dSph Connection from RR Lyrae Stars
G. Fiorentino, M. Monelli, P. B. Stetson +7
For the first time accurate pulsation properties of the ancient variable stars of the Fornax dwarf spheroidal galaxy (dSph) are discussed in the broad context of galaxy formation a…
Variable stars in Local Group Galaxies - II. Sculptor dSph
C. E. Martínez-Vázquez, P. B. Stetson, M. Monelli +9
We present the identification of 634 variable stars in the Milky Way dSph satellite Sculptor based on archival ground-based optical observations spanning 24 years and coverin…
GeMS MCAO observations of the Galactic globular cluster NGC 2808: the absolute age
Davide Massari, G. Fiorentino, A. McConnachie +7
Globular clusters are the oldest stellar systems in the Milky Way and probe the early epoch of the Galaxy formation. However, the uncertainties on their absolute age are still too…
