Abundances of CNO in candidate young metal-poor stars
Piercarlo Bonifacio, Elisabetta Caffau, Luca Sbordone +6
In this contribution we investigate the CNO abundances in five apparently young evolved stars, with the aim of discriminating between truly young stars and stars that were rejuvena…
HR-GO II: chemical abundances of low- retrograde dynamically-tagged-groups: Revealing Thamnos as a very metal-poor substructure
Renjing Xie, Zhen Yuan, Haining Li +12
Milky Way halo substructures identified in dynamical space are known to suffer from contamination from the Milky Way in-situ stars, which makes their accreted origins uncertain. We…
MINCE III. Detailed chemical analysis of the UVES sample
F. Lucertini, L. Sbordone, E. Caffau +14
Context. The MINCE (Measuring at Intermediate Metallicity Neutron-Capture Elements) project aims to provide high quality neutron-capture abundances measurements in several hundred…
Chemical Evolution of R-process Elements in Stars (CERES). III. Chemical abundances of neutron capture elements from Ba to Eu
L. Lombardo, C. J. Hansen, F. Rizzuti +11
The chemical abundances of elements such as barium and the lanthanides are essential to understand the nucleosynthesis of heavy elements in the early Universe as well as the contri…
HR-GO I: Comprehensive NLTE abundance analysis of the Cetus stream
T. M. Sitnova, Z. Yuan, T. Matsuno +8
Dwarf galaxy streams encode vast amounts of information essential to understanding early galaxy formation and nucleosynthesis channels. Due to the variation in the timescales of st…
High-speed stars. II. An unbound star, young stars, bulge metal-poor stars, and Aurora candidates
P. Bonifacio, E. Caffau, L. Monaco +6
The data from the Gaia satellite led us to revise our conception of the Galaxy structure and history. Hitherto unknown components have been discovered and a deep re-thinking of wha…
Chemical Evolution of R-process Elements in Stars (CERES). I. Stellar parameters and chemical abundances from Na to Zr
Linda Lombardo, Piercarlo Bonifacio, Patrick François +10
Aims. The Chemical Evolution of R-process Elements in Stars (CERES) project aims to provide a homogeneous analysis of a sample of metal-poor stars ([Fe/H]<-1.5). We present the ste…
Purveyors of fine halos III. Chemical abundance analysis of a potential omega Cen associate
Andreas J. Koch-Hansen, Camilla Juul Hansen, Linda Lombardo +3
Globular clusters (GCs) are important donors to the build-up of the Milky Way (MW) stellar halo, having contributed at the ten percent level over the Galactic history. Stars that o…
Purveyors of fine halos. II. Chemodynamical association of halo stars with Milky Way globular clusters
Michael Hanke, Andreas Koch, Zdenek Prudil +2
We present chemodynamical links between the present-day Milky Way halo field star population and Galactic globular clusters (GCs) using a dataset that combines information from the…
