Non-LTE analysis of the Si II lines in iota Her with various atomic data sets
L. Mashonkina, T. Sitnova, S. Korotin
This study shows that the statistical equilibrium of Si II in the atmosphere of a B3 IV type star iota Her is extremely sensitive to a variation in photoionization cross-sections f…
Abundance of beryllium in the Sun and stars: The role of non-local thermodynamic equilibrium effects
S. Korotin, A. Kučinskas
Earlier studies have suggested that deviations from the local thermodynamic equilibrium (LTE) play a minor role in the formation of Be II 313 nm resonance lines in solar and stella…
Abundance of zirconium in the globular cluster 47 Tuc: a possible Zr-Na correlation?
E. Kolomiecas, V. Dobrovolskas, A. Kučinskas +2
We determined abundances of Na and Zr in the atmospheres of 237 RGB stars in Galactic globular cluster (GGC) 47 Tuc (NGC 104), with a primary objective of investigating possible di…
Abundance of barium in the atmospheres of red giants in the Galactic globular cluster NGC 104 (47 Tuc)
V. Dobrovolskas, E. Kolomiecas, A. Kučinskas +2
Context. While most (if not all) Type I Galactic globular clusters (GGCs) are characterised by spreads in the abundances of light chemical elements (e.g. Li, N, O, Na, Mg, Al), it…
Light element abundances in the Galactic globular cluster 47 Tuc
A. Černiauskas, A. Kučinskas, P. Bonifacio +3
It is very likely that most (perhaps all) Galactic globular clusters (GGCs) have experienced two or even more star-formation episodes. This is indicated, in particular, by peculiar…
The NLTE Barium Abundance in Dwarf Stars in the Metallicity Range of -1 < [Fe/H] < +0.3
S. Korotin, T. Mishenina, T. Gorbaneva +1
We present the results of determination of the barium abundance considering the non-LTE (NLTE) effects in 172 dwarf stars in the metallicity range of -1< [Fe/H] <+0.3, assigned to…
