A new class of fossil fragments from the hierarchical assembly of the Galactic bulge
F. R. Ferraro, C. Pallanca, B. Lanzoni +12
The formation and evolutionary processes of galaxy bulges are still unclear, and the presence of young stars in the bulge of the Milky Way is largely debated. We recently demonstra…
On the Use of Field RR Lyrae as Galactic Probes. II. A new S calibration to estimate their metallicity
J. Crestani, M. Fabrizio, V. F. Braga +33
We performed the largest and most homogeneous spectroscopic survey of field RR Lyraes (RRLs). We secured 6,300 high resolution (HR, R35,000) spectra for 143 RRLs (11…
The diffuse interstellar band around 8620 Å I. Methods and application to the GIBS data set
H. Zhao, M. Schultheis, A. Recio-Blanco +6
We developed a set of procedures to automatically detect and measure the DIB around 8620 Å (the Gaia DIB) for a wide range of temperatures. The DIB profile is fit with a Gaussian f…
Mapping the stellar age of the Milky Way bulge with the VVV. III. High resolution reddening map
F. Surot, E. Valenti, O. A. Gonzalez +4
The detailed study of the Galactic bulge stellar population necessarily requires an accurate representation of the interstellar extinction particularly toward the Galactic plane an…
MOONS Surveys of the Milky Way and its Satellites
O. A. Gonzalez, A. Mucciarelli, L. Origlia +37
The study of resolved stellar populations in the Milky Way and other Local Group galaxies can provide us with a fossil record of their chemo-dynamical and star-formation histories…
On the Metamorphosis of the Bailey diagram for RR Lyrae stars
G. Bono, V. F. Braga, J. Crestani +37
We collected over 6000 high-resolution spectra of four dozen field RR Lyrae (RRL) variables pulsating either in the fundamental (39 RRab) or in the first overtone (9 RRc) mode. We…
