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…
Is Crater II disrupting?
A. Katherina Vivas, Alistair Walker, Clara Martínez-Vázquez +5
Crater~II (CraII) is a very intriguing, low-surface brightness and extended galaxy in the vicinity of our Milky Way. Motivated by its huge area and the number of RR Lyrae stars (RR…
The star formation history of the Sculptor dwarf spheroidal galaxy
Margherita Bettinelli, Sebastián L. Hidalgo, Santi Cassisi +4
We present the star formation history (SFH) of the Sculptor dwarf spheroidal galaxy based on deep g,r photometry taken with DECam at the Blanco telescope, focusing our analysis on…
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…
The Carina Project. VIII. The α-element abundances
M. Fabrizio, M. Nonino, G. Bono +16
We have performed a new abundance analysis of Carina Red Giant (RG) stars from spectroscopic data collected with UVES (high resolution) and FLAMES/GIRAFFE (high and medium resoluti…
