Title: “Detailed chemical abundances of Li to Eu in the F-G dwarfs of different metallicity as the observational constraints to the Galactic chemical evolution models”

Abstract:

We present results of the 5-year long work of a large team of collaborators from the four countries on the determination of atmospheric parameters and chemical abundances of Li to Eu for the F-G dwarf sample covering the metallicity range -2.7 < [Fe/H] < 0.3. The results are based on analysis of high-resolution spectral observations and the non-LTE line formation. The obtained elemental ratios are compared with the modern models of the Galactic chemical evolution.
