The Pristine survey XIII: Uncovering the very metal-poor tail of the thin disc
Emma Fernández-Alvar, Georges Kordopatis, Vanessa Hill +9
We evaluate the rotational velocity of stars observed by the Pristine survey towards the Galactic anticentre, spanning a wide range of metallicities from the extremely metal-poor r…
The Pristine Inner Galaxy Survey (PIGS) III: carbon-enhanced metal-poor stars in the bulge
Anke Arentsen, Else Starkenburg, David S. Aguado +15
The most metal-deficient stars hold important clues about the early build-up and chemical evolution of the Milky Way, and carbon-enhanced metal-poor (CEMP) stars are of special int…
The Pristine survey -- XII: Gemini-GRACES chemo-dynamical study of newly discovered extremely metal-poor stars in the Galaxy
Collin L. Kielty, Kim A. Venn, Federico Sestito +16
High-resolution optical spectra of 30 metal-poor stars selected from the \Pristine\ survey are presented, based on observations taken with the Gemini Observatory GRACES spectrograp…
The Pristine Inner Galaxy Survey (PIGS) II: Uncovering the most metal-poor populations in the inner Milky Way
Anke Arentsen, Else Starkenburg, Nicolas F. Martin +19
Metal-poor stars are important tools for tracing the early history of the Milky Way, and for learning about the first generations of stars. Simulations suggest that the oldest meta…
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…
The Pristine survey -- VII. A cleaner view of the Galactic outer halo using blue horizontal branch stars
Else Starkenburg, Kris Youakim, Nicolas Martin +11
We use the Pristine survey CaHK narrow-band photometry, combined with the SDSS ugr photometry, to provide a cleaner sample of blue horizontal branch stars in the Galactic halo out…
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…
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…
