The present common project of Bmo and Ondoejov stellar astronomers is aimed at the layout of current thorny problems of the physics of hot stars and stellar systems containing hot components. First, we want to contribute to elucidation of mutual relation among magnetic field geometry, spectroscopic and photometric spots or belts occurring on the surface of chemically peculiar (CP) stars. For the localization of spots of chemical elements by the analysis of their line profile variations a special techniqu of Doppler imaging will be used. Particularly, by means of a detailed study of a prototype of cool CP2 stars CQ UMa we want to solve the puzzle of the variable depression in energy distribution around 410 nm, typical for such a type of CP stars. Various hypotheses explaining the origin of Be-phenomenon will be tested by the observation of several B star with emission lines in their spectra. From the both theoretical and observational point of view will be studied extended atmospheres of hot stars and th
