... 2006: . ... 1) A study of the solar corona. ... 2) The study of the solar northern polar region. A powerful radio source above the solar North Pole in the region of the polar coronal hole was discovered. ... A transition boundary from brightening to darkening at the wavelength of 3.5cm was found in the emission of the polar coronal hole. These facts are decisive for the choice of the solar cycle model. 3) Polarized radio emission of a high-latitude prominence was registered. ... Archive . ...

... 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. ...
