VLT/FLAMES high-resolution chemical abundances in Sculptor: a textbook dwarf spheroidal galaxy
Vanessa Hill, Ása Skúladóttir, Eline Tolstoy +12
We present detailed chemical abundances for 99 red-giant branch stars in the centre of the Sculptor dwarf spheroidal galaxy, obtained from high-resolution VLT/FLAMES spectroscopy.…
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…
The Maunakea Spectroscopic Explorer Book 2018
Alexis Hill, Nicolas Flagey, Alan McConnachie +122
(Abridged) This is the Maunakea Spectroscopic Explorer 2018 book. It is intended as a concise reference guide to all aspects of the scientific and technical design of MSE, for the…
The R-Process Alliance: First Release from the Northern Search for r-Process Enhanced Metal-Poor Stars in the Galactic Halo
Charli M. Sakari, Vinicius M. Placco, Elizabeth M. Farrell +26
This paper presents the detailed abundances and r-process classifications of 126 newly identified metal-poor stars as part of an ongoing collaboration, the R-Process Alliance. The…
A-type stars in the Canada-France Imaging Survey II. Tracing the height of the disc at large distances with Blue Stragglers
Guillaume F. Thomas, Chervin F. P. Laporte, Alan W. McConnachie +7
We present the kinematics of Blue Straggler (BS) stars identified in the Canada-France-Imaging-Survey (CFIS), covering 4000 deg on the sky in the -band. The BS sample, chara…
Chemical Abundances in the Ultra-Faint Dwarf Galaxies Grus I and Triangulum II: Neutron-Capture Elements as a Defining Feature of the Faintest Dwarfs
Alexander P. Ji, Joshua D. Simon, Anna Frebel +2
We present high-resolution of spectroscopy of four stars in two candidate ultra-faint dwarf galaxies (UFDs) Grus I (Gru I) and Triangulum II (Tri II). Neither object currently has…
