The Fifteenth Data Release of the Sloan Digital Sky Surveys: First Release of MaNGA Derived Quantities, Data Visualization Tools and Stellar Library
D. S. Aguado, Romina Ahumada, Andres Almeida +230
Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years o…
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…
Chemical analysis of very metal-poor turn-off stars from SDSS-DR12
P. François, E. Caffau, S. Wanajo +7
The most metal-poor stars are the relics of the early chemical evolution of the Galaxy. Their chemical composition is an important tool to constrain the nucleosynthesis in the firs…
Pristine Dwarf-Galaxy Survey I: A detailed photometric and spectroscopic study of the very metal-poor Draco II satellite
Nicolas Longeard, Nicolas Martin, Else Starkenburg +17
We present a detailed study of the faint Milky Way satellite Draco II (Dra II) from deep CFHT/MegaCam broadband and photometry and narrow-band metallicity-sensitive CaHK ob…
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…
Two planetary systems with transiting Earth-size and super-Earth planets orbiting late-type dwarf stars
E. Diez Alonso, J. I. Gonzalez Hernandez, S. L. Suarez Gomez +9
We present two new planetary systems found around cool dwarf stars with data from the K2 mission. The first system was found in K2-239 (EPIC 248545986), char- acterized in this wor…
