Ari with the amplitude ± 41 m/s are found, the program of calculation of synthetic spectra of stars is remade, ~700 spectra gained on VLT are handled, radial velocities of lines of various chemical elements are measured and the frequency analysis of the found radial velocities is made, operation on integration of the archival information which have been saved up in the databases in scientific research institute "CrАО" intended for on-line uses is prolonged, results of broadband photometer observations of eclipse systems V2291 Ophiuchi are converted into uniform system, operation on making the spectrophotometric catalogue of the stars observed in CrAO in 1972-1989 is prolonged.
