... A method to detect non-radial pulsations of CP stars is suggested. ... The opportunity is noted to get an information on spatial structure of non-radial oscillations from the analysis of radial velocities of chemical element lines, concentrated in the spots. To detect and identify the modes of non-radial oscillations of average grades it is suggested to use the methods of line profile analysis applying thee to the lines observed in the local spots on the stellar surface. ...

... Accurate identification of physical binary star systems has become of increasing interest in recent years. ... Identification of physical binary star systems, with an estimated reliability of such identifications based on the theory of probability, is also important for current and future efforts to find binary star systems that are candidates for observations with the aim of determining their orbits and component masses. ... probability of the proximity of proper motions and ; . ...
