Disentangling multiple stellar populations in globular clusters using the Strömgren system
J. Alonso-García, M. Catelan, P. Amigo +10
An increasing amount of spectroscopic and photometric evidence is showing that the stellar populations of globular clusters are not as simple as they have been considered for many…
Milky Way demographics with the VVV survey. I. The 84-million star colour-magnitude diagram of the Galactic bulge
R. K. Saito, D. Minniti, B. Dias +9
The Milky Way (MW) bulge is a fundamental Galactic component for understanding the formation and evolution of galaxies, in particular our own. The ESO Public Survey VISTA Variables…
Stellar Archaeology in the Galactic halo with Ultra-Faint Dwarfs: VII. Hercules
Ilaria Musella, Vincenzo Ripepi, Marcella Marconi +13
We present the first time-series study of the ultra-faint dwarf galaxy Hercules. Using a variety of telescope/instrument facilities we secured about 50 V and 80 B epochs. These dat…
Stellar Archaeology in the Galactic halo with the Ultra-Faint Dwarfs: VI. Ursa Major II
M. Dall'Ora, K. Kinemuchi, V. Ripepi +11
We present a B, V color-magnitude diagram (CMD) of the Milky Way dwarf satellite Ursa Major II (UMa II), spanning the magnitude range from V ~ 15 to V ~ 23.5 mag and extending over…
Detailed abundances in stars belonging to ultra-faint dwarf spheroidal galaxies
P. François, L. Monaco, S. Villanova +7
We report preliminary results concerning the detailed chemical composition of metal poor stars belonging to close ultra-faint dwarf galaxies (hereafter UfDSphs). The abundances hav…
