Unveiling the nature of HE 0107-5240
E. Caffau, M. Steffen, P. Molaro +27
The vast majority of the most iron-poor stars in the Galaxy exhibit a strong carbon enhancement, with C/H ratios only about two orders of magnitude below solar. This unusual chemic…
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…
SDSS J102915.14+172927.9: Revisiting the chemical pattern
E. Caffau, P. Bonifacio, L. Monaco +7
Context: The small- to intermediate-mass (), most metal-poor stars that formed in the infancy of the Universe are still shining today in the sky. They are very rare…
MINCE II. Neutron capture elements
P. François, G. Cescutti, P. Bonifacio +24
The MINCE (Measuring at Intermediate metallicity Neutron-Capture Elements) project aims to gather the abundances of neutron-capture elements but also of light elements and iron pea…
Mono-enriched stars and Galactic chemical evolution -- Possible biases in observations and theory
Camilla Juul Hansen, Andreas Koch, Lyudmila Mashonkina +9
A long sought after goal using chemical abundance patterns derived from metal-poor stars is to understand the Galactic chemical evolution (GCE) and to pin down the nature of the fi…
The Gaia-ESO survey: 3D NLTE abundances in the open cluster NGC 2420 suggest atomic diffusion and turbulent mixing at the origin of chemical abundance variations
Ekaterina Semenova, Maria Bergemann, Morgan Deal +10
Atomic diffusion and mixing processes in stellar interiors influence the structure and the surface composition of stars. Some of these processes cannot yet be modelled from the fir…
