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…
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…
