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…
The Pristine Survey IV: Approaching the Galactic metallicity floor with the discovery of an ultra metal-poor star
Else Starkenburg, David S. Aguado, Piercarlo Bonifacio +22
The early Universe presented a star formation environment that was almost devoid of heavy elements. The lowest metallicity stars thus provide a unique window into the earliest Gala…
Climbing the cosmic ladder with stellar twins in RAVE with Gaia
P. Jofre, G. Traven, K. Hawkins +17
We apply the twin method to determine parallaxes to 232,545 stars of the RAVE survey using the parallaxes of Gaia DR1 as a reference. To search for twins in this large dataset, we…
Very metal-poor stars observed by the RAVE survey
