Kinematic and metallicity properties od the Aquarius dwarf galaxy from FORS2 MXU spectroscopy

L. Hermosa Muñoz, S. Taibi, G. Battaglia +10

Dwarf galaxies found in isolation in the Local Group (LG) are unlikely to have interacted with the large LG spirals, and therefore environmental effects should not be the main driv…

The Pristine survey X: a large population of low-metallicity stars permeates the Galactic disk

Federico Sestito, Nicolas F. Martin, Else Starkenburg +26

The orbits of the least chemically enriched stars open a window on the formation of our Galaxy when it was still in its infancy. The common picture is that these low-metallicity st…

The chemical evolution of the dwarf Spheroidal galaxy Sextans

R. Theler, P. Jablonka, R. Lucchesi +11

We present the analysis of the FLAMES dataset targeting the central 25 arcmin region of the Sextans dSph. This dataset is the third major part of the high resolution spectroscopic…

The Pristine Survey -- VI. The first three years of medium-resolution follow-up spectroscopy of Pristine EMP star candidates

David S. Aguado, Kris Youakim, Jonay I. González Hernández +27

We present the results of a 3-year long, medium-resolution spectroscopic campaign aimed at identifying very metal-poor stars from candidates selected with the CaHK, metallicity-sen…

The HST/ACS star formation history of the Tucana dwarf spheroidal galaxy: clues from the horizontal branch

A. Savino, E. Tolstoy, M. Salaris +2

We report a new star formation history for the Tucana dwarf spheroidal galaxy, obtained from a new look at a deep HST/ACS colour-magnitude diagram. We combined information from the…

Stellar 3-D kinematics in the Draco dwarf spheroidal galaxy

Davide Massari, Amina Helmi, Alessio Mucciarelli +3

Aims. We present the first three-dimensional internal motions for individual stars in the Draco dwarf spheroidal galaxy. Methods. By combining first-epoch $Telesco…
