... Iron abundance in the atmospheres of components of the binary system 41 Draconis . ... 5B Iron abundances, FeI and FeII lines equivalent widths, and microturbulence velocities were found for the components of a highly eccentric spectroscopic and interferometric binary system 41 Dra from high resolution spectra obtained close to the periastron. Weighted mean values of iron abundances in the atmospheres are lgN(Fe) = 7.66 ± 0.03 and lgN(Fe) = 7.72 ± 0.03 for the component a and b, correspondingly. ...
