Barium Abundances in Cepheids
S. M. Andrievsky, J. R. D. Lepine, S. A. Korotin +3
We derived the barium atmospheric abundances for a large sample of Cepheids, comprising 270 stars. The sample covers a large range of galactocentric distances, from about 4 to 15 k…
NLTE determination of the calcium abundance and 3D corrections in extremely metal-poor stars
Monique Spite, S. M. Andrievsky, F. Spite +6
(Abridged) Extremely metal-poor stars contain the fossil records of the chemical composition of the early Galaxy. The NLTE profiles of the calcium lines were computed in a sample o…
Barium abundance in red giants of NGC 6752. Non-local thermodynamic equilibrium and three-dimensional effects
V. Dobrovolskas, A. Kučinskas, S. M. Andrievsky +5
(Abridged) Aims: We study the effects related to departures from non-local thermodynamic equilibrium (NLTE) and homogeneity in the atmospheres of red giant stars in Galactic globul…
