... 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. ...

... Recent studies indicate that stars are most likely forming within the binary and multiple systems. ... During several years we are conducting the observations of such multiple stellar systems at the BTA telescope in order to find their companions and study the properties therein. ... This star is interesting in that it may be a dynamically unstable multiple star, meaning that over time, such systems will split into individual stars. ... A bright component is a very tight spectroscopic binary star. ...
