TOPoS VII. Age-metallicity relation in the Galactic halo and assembly of the Milky Way
P. Bonifacio, Y. Lebreton, I. Koutsouridou +8
One technique for determining stellar ages is to compare the position of a star in the Hertzsprung-Russell diagram to theoretical stellar evolutionary tracks. The sub-giant evoluti…
TYC 170-1218-1: A new r-process-enhanced extremely metal-poor star, rich in Th
E. Caffau, P. Bonifacio, L. Sbordone +5
Context . Extremely metal-poor (EMP) stars are formed from gas clouds enriched by one or a few supernova explosions belonging to the first stellar generation and this very limited…
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…
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…
Neutron-capture elements in a sample of field metal-poor N-rich dwarfs
M Spite, P Bonifacio, E Caffau +1
The aim of this work is to measure the abundances of n-capture elements in a sample of six metal-poor N-rich dwarfs that were formed in globular clusters, and subsequently became u…
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…
