. The seminar is supported by the grant of Federal Programm "Integration" . annotation of talk . S.Ibadov (Astrophys. Inst, Tadjikistan) . "Generation of X-ray in Comets" . Generation of X-rays in comets due to production of high-temperature plasma blobs from collisions of cometary and zodiacal dust particles is being considered. Observations of dusty comets in the zone of small heliocentric distances (R<1AU) by the ROSAT and XMM-type X-ray telescopes seem warranted.
