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…
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…
The Pristine survey. XXVI. Chemical abundances of subgiant stars of the extremelymetal-poor stream C-19
P. Bonifacio, E. Caffau, P. François +17
Context: The C-19 stellar stream is the most metal-poor stream known to date. While its width and velocity dispersion indicate a dwarf galaxy origin, its metallicity spread and abu…
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…
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…
The Gaia RVS benchmark stars II. A sample of stars selected for their Gaia high radial velocity
E. Caffau, D. Katz, A. Gómez +16
The Gaia satellite has already provided the astronomical community with three data releases, and the Radial Velocity Spectrometer (RVS) on board Gaia has provided the radial veloci…
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…
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…
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…
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…
Abundance ratios of red giants in low mass ultra faint dwarf spheroidal galaxies
P. François, L. Monaco, P. Bonifacio +3
Low mass dwarf spheroidal galaxies are key objects for our understanding of the chemical evolution of the pristine Universe and the Local Group of galaxies. Abundance ratios in sta…
NLTE determination of the sodium abundance in a homogeneous sample of extremely metal-poor stars
S. M. Andrievsky, M. Spite, S. A. Korotin +5
Abundance ratios in extremely metal-poor (EMP) stars are a good indication of the chemical composition of the gas in the earliest phases of the Galaxy evolution. It had been found…
