The Pristine survey -- XVII. The C-19 stream is dynamically hot and more extended than previously thought
Zhen Yuan, Nicolas F. Martin, Rodrigo A. Ibata +22
The C-19 stream is the most metal poor stellar system ever discovered, with a mean metallicity . Its low metallicity dispersion ( 0.18 at…
First detection of a magnetic field in low-luminosity B[e] stars: New scenarios for the nature and evolutionary stages of FS CMa stars
D. Korcakova, F. Sestito, N. Manset +8
We report the first detection of the magnetic field in a star of FS CMa type, a subgroup of objects characterized by the B[e] phenomenon. The split of magnetically sensitive lines…
A stellar stream remnant of a globular cluster below the metallicity floor
Nicolas F. Martin, Kim A. Venn, David S. Aguado +23
Stellar ejecta gradually enrich the gas out of which subsequent stars form, making the least chemically enriched stellar systems direct fossils of structures formed in the early un…
The Pristine survey XIV: chemical analysis of two ultra-metal-poor stars
C. Lardo, L. Mashonkina, P. Jablonka +15
Elemental abundances of the most metal-poor stars reflect the conditions in the early Galaxy and the properties of the first stars. We present a spectroscopic follow-up of two ultr…
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 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…
