- Аннотация: We analyse the dispersion of Li in the atmosphere of 56 solar type stars including 22 solar twins. Lithium abundances are derived by comparing observed and synthetic spectra in the region of Li I line 6707 A, taking into account NLTE corrections. We discuss the observed scatter in Li abundance of solar twins as afunction of age, rotation velocity, and other factors. We compare to the predictions of stellar evolution models which include different transport processes for angular momentum and chemicals.
