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…

Preliminary Target Selection for the DESI Milky Way Survey (MWS)

Carlos Allende Prieto, Andrew P. Cooper, Arjun Dey +31

The DESI Milky Way Survey (MWS) will observe 8 million stars between mag, supplemented by observations of brighter targets under poor observing conditions. The s…

The S2 Stream: the shreds of a primitive dwarf galaxy

David S. Aguado, G. C. Myeong, Vasily Belokurov +12

The S2 stream is a kinematically cold stream that is plunging downwards through the Galactic disc. It may be part of a hotter and more diffuse structure called the Helmi stream. We…

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 extreme CNO-enhanced composition of the primitive iron-poor dwarf star J0815+4729

Jonay I. González Hernández, David S. Aguado, Carlos Allende Prieto +2

We present an analysis of high-resolution Keck/HIRES spectroscopic observations of J0815+4729, an extremely carbon-enhanced, iron-poor dwarf star. These high-quality data allow us…
