Abundances of lithium, oxygen, and sodium in the turn-off stars of Galactic globular cluster 47 Tuc
V. Dobrovolskas, A. Kučinskas, P. Bonifacio +7
We aim to determine abundances of Li, O and Na in a sample of of 110 turn-off (TO) stars, in order to study the evolution of light elements in this cluster and to put our results i…
The influence of convection on the atmospheric structures and observable properties of red giant stars
A. Kucinskas, H. -G. Ludwig, M. Steffen +5
During the recent years significant progress has been made in the modeling of red giant atmospheres with the aid of 3D hydrodynamical model atmosphere codes. In this contribution w…
Spectral line asymmetries in the metal-poor red giant HD 122563: CO5BOLD predictions versus observations
J. Klevas, A. Kucinskas, H. -G. Ludwig +3
We study the influence of convection on the asymmetries and Doppler shifts of Fe I spectral lines in the metal-poor red giant HD 122563. To this end, we compute theoretical Fe I li…
Oxygen spectral line synthesis: 3D non-LTE with CO5BOLD hydrodynamical model atmospheres
D. Prakapavicius, M. Steffen, A. Kucinskas +4
In this work we present first results of our current project aimed at combining the 3D hydrodynamical stellar atmosphere approach with non-LTE (NLTE) spectral line synthesis for a…
