MINCE IV. A detailed analysis of 37 metal-poor and subsolar metallicity stars
L. Sgatti, G. Cescutti, L. Lombardo +13
The project called Measuring at Intermediate metallicity Neutron-Capture Elements (MINCE) primarily focuses on the photospheric abundances of several neutron-capture (NC) elements…
Gaia DR3 high radial velocity stars: Genuine fast-moving objects or outliers?
D. Katz, A. Gómez, E. Caffau +39
The third Gaia data release includes 33.8 million radial velocity measurements, extending to a magnitude of G_RVS = 14. To reach this magnitude limit, spectra were processed down t…
Unlocking the mystery of Sr synthesis in the early Galaxy through analysis of barium isotopes in very metal-poor stars
T. M. Sitnova, L. Lombardo, L. I. Mashonkina +8
We determine the contributions of the rapid (r) and slow (s) neutron capture processes to the Ba isotope mixture, along with Ba, Eu, and Sr NLTE abundances, in a sample of very met…
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…
High speed stars: III. Detailed abundances and binary nature of the extreme speed star GHS143
E. Caffau, P. Bonifacio L. Monaco, L. Sbordone +7
The Gaia satellite has provided the community with three releases containing astrometrical and photometric data as well as by products, such as stellar parameters and variability i…
On the 12C/13C isotopic ratio at the dawn of chemical evolution
P. Molaro, D. S. Aguado, E. Caffau +21
The known Mega and Hyper Metal-Poor (MMP-HMP) stars with [Fe/H]<-6.0 and <-5.0, respectively, likely belong to the CEMP-no class, i.e. carbon-enhanced stars with low or absent seco…
Young giants of intermediate mass Evidence of rotation and mixing
Linda Lombardo, Patrick François, Piercarlo Bonifacio +7
In the search of a sample of metal-poor bright giants using Str{ö}mgren photometry, we serendipitously found a sample of 26 young (ages younger than 1 Gyr) metal-rich giants, some…
