Abstract
Thesis work:50pp,14 figures,4 tables, 17sources,4 appendices. Visual binary stars, observation methods, speckle interferometric measurements, orbit, orbit elements. The object of study is visual binary stars. The aim of the work is to process speckle interferometric observations, construct an orbit, estimate stellar masses and linear dimensions of the orbit. High – precision measurements of the binary star Lyr have been completed Lyr. Speckle interferometric observation were processed using an analog method using the coherent optical setup as JSC KhSU. Image scale calibration was performed using an interferometric scheme. New orbits have been calculated. A 14-year orbit for 6 Neg has been calculated for the first time. The orbit was constructed using a method of expanding the rectangular components of the orbit motion into Fourier series. The calculations were performed on the lskra-1030 PPEM. The methods of image scale calibration, position angle referencing and orbit constructing method will be used in the further program of binary star observations.
