The star 12 Per is known as a spectroscopic and interferometeric binary. The high resolution spectra in 3700 - 8000 Å band were obtained with the 2 m telescope at Peak Terskol. A detailed analysis of the atmosphere of system's components was carried

The speckle interferometric binary system Gl 150.2 (HIP17491) is analyzed using atmosphere modeling and dynamical analysis simultaneously. A synthetic spectral energy distribution (SED) for each of the two components of the system is built using Kuru

Atmospheric modeling is used to build synthetic spectral energy distributions (SEDs) for the individual components of the speckle interferometric binary system HD375. These synthetic SEDs are combined together for the entire system and compared with

We succeeded in separating the absorption lines of both the primary C1 and the secondary C2 component in the spectra of the young massive binary θ 1 OriC (O6Vp + B0V, mass sum 44 ± 7M ⊙), obtained during the period from November 1995 to February

Chemical anomalies observed in some binary stars are analyzed. These anomalies are caused by: (1) nuclear processes in their cores; (2) diffusive and convective mixing of material between neighboring layers with nuclear heating; and, (3) ejection of

The system 12 Per is a spectroscopic and speckle-interferometric binary with the components of similar spectral classes. The parameters of its orbit were determined quite accurately over nearly a century of observations. To refine the atmospheric abu

We present a study of stratification of helium and silicon in the atmospheres of CP stars HD 168785 (He-r) and HD 21699 (He-w). The distribution of these elements with depth is well described by the mechanism of diffusion under the effect of gravity,

HD 10009 is a spectroscopic and speckle interferometric binary with almost identical solar-type components. It was studied via speckle interferometry using the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences

We have performed speckle interferometry with the 6-m telescope of the Special Astrophysical Observatory and spectroscopy (at 3700–9200 A) with the 2-m telescope at Peak Terskol of the spectroscopic and interferometric binary 9 Cyg, which is a comp
