On the Pair-Instability Supernova origin of J1010+2358
Ása Skúladóttir, Ioanna Koutsouridou, Irene Vanni +4
The first (Pop III) stars formed only out of H and He and were likely more massive than present-day stars. Massive Pop III stars in the range 140-260 M are predicted to end…
The Pristine Dwarf-Galaxy survey -- III. Revealing the nature of the Milky Way globular cluster Sagittarius II
Nicolas Longeard, Nicolas Martin, Rodrigo Ibata +13
We present a new spectroscopic study of the faint Milky Way satellite Sagittarius II. Using multi-object spectroscopy from the Fibre Large Array Multi Element Spectrograph, we supp…
Homogeneity in the early chemical evolution of the Sextans dwarf Spheroidal galaxy
R. Lucchesi, C. Lardo, F. Primas +10
We present the high-resolution spectroscopic analysis of two new extremely metal-poor stars (EMPS) candidates in the dwarf spheroidal galaxy Sextans. These targets were pre-selecte…
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…
