Exploring the s-process history in the Galactic disk: Cerium abundances and gradients in Open Clusters from the OCCAM/APOGEE sample
J. V. Sales-Silva, S. Daflon, K. Cunha +21
The APOGEE Open Cluster Chemical Abundances and Mapping (OCCAM) survey is used to probe the chemical evolution of the s-process element cerium in the Galactic disk. Cerium abundanc…
Photo-astrometric distances, extinctions, and astrophysical parameters for Gaia EDR3 stars brighter than G=18.5
F. Anders, A. Khalatyan, A. B. A. Queiroz +23
We present a catalogue of 362 million stellar parameters, distances, and extinctions derived from Gaia's early third data release (EDR3) cross-matched with the photometric catalogu…
APOGEE-2 Discovery of a Large Population of Relatively High-Metallicity Globular Cluster Debris
José G. Fernández-Trincado, Timothy C. Beers, Anna. B. A. Queiroz +13
We report the discovery of a new, chemically distinct population of relatively high-metallicity ([Fe/H] ) red giant stars with super-solar [N/Fe] () identifi…
Photo-chemo-dynamical analysis and the origin of the bulge globular cluster Palomar 6
Stefano O. Souza, Marica Valentini, Beatriz Barbuy +7
Palomar 6 (Pal~6) is a moderately metal-poor globular cluster projected towards the Galactic bulge. A full analysis of the cluster can give hints on the early chemical enrichment o…
Barium lines in high-quality spectra of two metal-poor giants in the Galactic halo
G. Cescutti, C. Morossi, M. Franchini +9
Context. Theoretical results showed the possibility that neutron capture elements were produced in the early Universe by two different sources: a frequent s-process source hosted b…
Deciphering the evolution of the Milky Way discs: Gaia APOGEE Kepler giant stars and the Besançon Galaxy Model
N. Lagarde, C. Reylé, C. Chiappini +13
We investigate the properties of the double sequences of the Milky Way discs visible in the [/Fe] vs [Fe/H] diagram. In the framework of Galactic formation and evolution, we dis…
