Tracing the formation of the Milky Way through ultra metal-poor stars
Federico Sestito, Nicolas Longeard, Nicolas F. Martin +11
We use Gaia DR2 astrometric and photometric data, published radial velocities and MESA models to infer distances, orbits, surface gravities, and effective temperatures for all ultr…
Chemical analysis of very metal-poor turn-off stars from SDSS-DR12
P. François, E. Caffau, S. Wanajo +7
The most metal-poor stars are the relics of the early chemical evolution of the Galaxy. Their chemical composition is an important tool to constrain the nucleosynthesis in the firs…
Pristine Dwarf-Galaxy Survey I: A detailed photometric and spectroscopic study of the very metal-poor Draco II satellite
Nicolas Longeard, Nicolas Martin, Else Starkenburg +17
We present a detailed study of the faint Milky Way satellite Draco II (Dra II) from deep CFHT/MegaCam broadband and photometry and narrow-band metallicity-sensitive CaHK ob…
