dc.description.abstract | In order to shed new light on the dispersion of Li in the atmosphere of solar type stars, a set of 56 solar analogs including 22 solar twins is analysed. Lithium abundances are derived by comparing observed and synthetic spectra in the region of Li I line 6707 Å in LTE approximation. The behavior of Li abundances as a function of the effective temperature Teff, age, rotational velocities vsini and chromospheric activity log R’HK is discussed in the context of stellar and galactic evolution. | uk_UA |
