Andronov, Registration Date 10-03-2020 Organization Odessa national maritime university popup.description2 The characteristics of the variability of a group of magnetic cataclysmic binary stellar systems are determined and refined. The variability characteristics of a group of eclipsing systems with matter flow and surrounding third bodies in elliptical orbits are investigated. Catalogues of variability characteristics and atlases of light curves for groups of long-period pulsating and eclipsing stars have been created. Positron annihilation in young supernova remnants is considered. New advanced algorithms and computer programs MAVKA, NAV have been developed, which allow to obtain a phenomenological approximation of the brightness curves better than the previous counterparts, respectively, for short series near extrema and full darkness curves. An FVSE computer program has been created to search for new CCD stars, images of starry sky regions. A photometric survey of selected areas of the celestial sphere was performed with the help of terrestrial and space telescopes in order to assess the physical parameters of some systems of variable stars. The database of photometric observations of objects of study is updated. Some physical parameters have been reduced to the newly created catalog of stars. Implementation of completed developments in physical and mathematical disciplines contributes to a deeper study of mathematics, physics and statistics, which can be further applied to graduates in the field of management of the public service of maritime and river transport of Ukraine. 10 papers have been published in journals listed in SCOPUS and WoS. Applications are: astronomy, astrophysics, astroinformatics, information technology, computer science.
