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…
Pristine IX: CFHT ESPaDOnS Spectroscopic Analysis of 115 Bright Metal-Poor Candidate Stars
Kim Venn, Collin Kielty, Federico Sestito +18
A chemo-dynamical analysis of 115 metal-poor candidate stars selected from the narrow-band Pristine photometric survey is presented based on CFHT high-resolution ESPaDoNS spectrosc…
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…
Chemo-dynamical properties of the Anticenter Stream: a surviving disc fossil from a past satellite interaction
Chervin F. P. Laporte, Vasily Belokurov, Sergey E. Koposov +2
Using Gaia DR2, we trace the Anticenter Stream (ACS) in various stellar populations across the sky and find that it is kinematically and spatially decoupled from the Monoceros Ring…
The Detailed Science Case for the Maunakea Spectroscopic Explorer, 2019 edition
The MSE Science Team, Carine Babusiaux, Maria Bergemann +258
(Abridged) The Maunakea Spectroscopic Explorer (MSE) is an end-to-end science platform for the design, execution and scientific exploitation of spectroscopic surveys. It will unvei…
The birth of the Milky Way as uncovered by accurate stellar ages with Gaia
Carme Gallart, Edouard J. Bernard, Chris B. Brook +4
Knowledge of ages for stars formed over a galaxy's lifetime is fundamental to understand its formation and evolution. However, stellar ages are difficult to obtain since they canno…
