A Wide Metallicity Range for Gyr-old Stars in the Nuclear Star Cluster
Brian Thorsbro, Rebecca Forsberg, Georges Kordopatis +6
We report metallicities for three Gyr-old stars in the Milky Way nuclear star cluster (NSC) using high-resolution near-infrared spectroscopy. We derive effective temperatures…
Gaia Focused Product Release: Spatial distribution of two diffuse interstellar bands
Gaia Collaboration, M. Schultheis, H. Zhao +15
Diffuse interstellar bands (DIBs) are absorption features seen in optical and infrared spectra of stars that are probably caused by large and complex molecules in the ISM. Here we…
A stellar stream remnant of a globular cluster below the metallicity floor
Nicolas F. Martin, Kim A. Venn, David S. Aguado +23
Stellar ejecta gradually enrich the gas out of which subsequent stars form, making the least chemically enriched stellar systems direct fossils of structures formed in the early un…
The Pristine survey XIV: chemical analysis of two ultra-metal-poor stars
C. Lardo, L. Mashonkina, P. Jablonka +15
Elemental abundances of the most metal-poor stars reflect the conditions in the early Galaxy and the properties of the first stars. We present a spectroscopic follow-up of two ultr…
The diffuse interstellar band around 8620 Å II. Kinematics and distance of the DIB carrier
H. Zhao, M. Schultheis, A. Rojas-Arriagada +4
We aim to make use of the measurements from the Giraffe Inner Bulge Survey (GIBS) and the GaiaESO survey (GES) to study the kinematics and distance of the carrier of DIB862…
The AMBRE Project: Solar neighbourhood chemodynamical constraints on Galactic disc evolution
Pablo Santos-Peral, Alejandra Recio-Blanco, Georges Kordopatis +2
We analysed the chemodynamical evolution of the Galactic disc using precise [Mg/Fe] abundances from a previous study and accurate Gaia data. For this purpose, we estimated ages and…
