Evolution of the Barium abundance in the early Galaxy from a NLTE analysis of the Ba lines in a homogeneous sample of EMP stars
S. M. Andrievsky, M. Spite, S. A. Korotin +5
Barium is a key element in constraining the evolution of the (not well understood) r-process in the first galactic stars and currently the Ba abundances in these very metal-poor st…
Open clusters as key tracers of Galactic chemical evolution. III. Element abundances in Berkeley 20, Berkeley 29, Collinder 261, and Melotte 66
P. Sestito, A. Bragaglia, S. Randich +3
Galactic open clusters are since long recognized as one of the best tools for investigating the radial distribution of iron and other metals. We employed FLAMES at VLT to collect U…
Reddenings of FGK supergiants and classical Cepheids from spectroscopic data
V. V. Kovtyukh, C. Soubiran, R. E. Luck +4
Accurate and homogeneous atmospheric parameters (Teff, log (g), Vt, [Fe/H]) are derived for 74 FGK non-variable supergiants from high-resolution, high signal-to-noise ratio, echell…
NLTE determination of the aluminium abundance in a homogeneous sample of extremely metal-poor stars
S. M. Andrievsky, M. Spite, S. A. Korotin +5
Aims: Aluminium is a key element to constrain the models of the chemical enrichment and the yields of the first supernovae. But obtaining precise Al abundances in extremely metal-p…
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…
