Federico Sestito,Federico Sestito,Nicolas Longeard,Nicolas F. Martin,Nicolas F. Martin,Else Starkenburg,Morgan Fouesneau,Jonay I. González Hernández,Jonay I. González Hernández,Anke Arentsen,Rodrigo A. Ibata,David Aguado,Raymond G. Carlberg,Pascale Jablonka,Pascale Jablonka,Julio F. Navarro,Eline Tolstoy,Kim A. Venn +17 more
TL;DR: In this article, the authors used Gaia DR2 data, published radial velocities and MESA models to infer distances, orbits, surface gravities, and effective temperatures for all ultra metal-poor stars.
Journal ArticleDOI

TL;DR: Pristine_2218781+97844 was discovered using narrow-band CaHK in this paper, and it is very similar to the most metal-poor star known (SDSS J102915+172927).
Journal ArticleDOI

TL;DR: The results of a 3-yr long, medium-resolution spectroscopic campaign aimed at identifying very metal -poor stars from candidates selected with the CaHK, metallicity sensitive Pristine survey are presented in this article.
Journal ArticleDOI
The Pristine Survey – VIII. The metallicity distribution function of the Milky Way halo down to the extremely metal-poor regime

TL;DR: The Pristine survey as mentioned in this paper uses narrow-band photometry to derive precise metallicities down to the extremely metal-poor regime ( [Fe/H] < -3), and currently consists of over 4 million FGK-type stars over a sky area of ˜ 2500 deg^2.
Journal ArticleDOI

TL;DR: In this article, the authors used the Pristine and LAMOST surveys and Gaia DR2 parallaxes and proper motions for an unprecedented large and unbiased sample of 1027 very metal poor stars at [Fe/H] ≤ -2.5 dex, and they showed strong statistical evidence (at the 5.0σ level) of asymmetry in their kinematics, favoring prograde motion.
