GIANO Y-band spectroscopy of dwarf stars: Phosphorus, Sulphur, and Strontium abundances
E. Caffau, S. Andrievsky, S. Korotin +5
In recent years a number of poorly studied chemical elements, such as phosphorus, sulphur, and strontium, have received special attention as important tracers of the Galactic chemi…
High-resolution abundance analysis of HD 140283
C. Siqueira-Mello, S. M. Andrievsky, B. Barbuy +3
HD 140283 is a reference subgiant that is metal poor and confirmed to be a very old star. The abundances of this type of old star can constrain the nature and nucleosynthesis proce…
Grid of theoretical NLTE equivalent widths of four Ba II lines and barium abundance in cool stars
S. A. Korotin, S. M. Andrievsky, C. J. Hansen +5
We present a grid of computed non-local thermodynamic equilibrium (NLTE) equivalent widths (EW) and NLTE abundance corrections for four Ba II lines: 4554, 5853, 6141, and 6496 A. T…
Chemical abundances of giant stars in the Crater stellar system
P. Bonifacio, E. Caffau, S. Zaggia +4
We obtained spectra for two giants of Crater (Crater J113613-105227 and Crater J113615-105244) using X-Shooter at the VLT. The spectra have been analysed with the MyGIsFoS code usi…
Sulphur in the Sculptor dwarf spheroidal galaxy - Including NLTE corrections
Asa Skuladottir, Sergei M. Andrievsky, Eline Tolstoy +4
In Galactic halo stars, sulphur has been shown to behave like other -elements, but until now, no comprehensive studies have been done on this element in stars of other galaxies.…
Oxygen, α-element and iron abundance distributions in the inner part of the Galactic thin disc
R. P. Martin, S. M. Andrievsky, V. V. Kovtyukh +3
We derived elemental abundances in 27 Cepheids, the great majority situated within a zone of Galactocentric distances ranging from 5 to 7 kpc. One star of our sample, SU Sct, has a…
