Karazin popup.description2 Object of the research is stellar populations of the Galaxy and extragalactic objects. Method of the research is observational data processing, mathematical methods of statistics, generalization and comparative data analysis, the least square method, filtering and approximating data. The results are present in 21 publications (10 abstracts, 11 articles) as well as 10 oral talks at 6 different international conferences. The main goal of the second stage of the project is classification of stars into different spectral classes and selection of objects which do not belong to our Galaxy. Analysis of the Galactic kinematics is mainly connected with statistical analysis of stellar proper motions from modern astrometric catalogues as well as choosing the most accurate one for further research. Then it is necessary to fulfil detailed study of kinematic parameters of different Galactic subsystems (thin and thick disks, halo, red clump giants). Also it is necessary to classify stellar objects into those belonging to our Galaxy and extragalactic sources (quasars, AGN and other far galaxies). Contamination of data under analysis by objects of extragalactic origin affects significantly the results of kinematic analysis especially in the faint range of magnitudes where extragalactic objects contribute significantly to the stellar velocity field. Usage of artificial neuron networks for analysing data of modern photometric surveys such as ALLWISE and Pan-STARRS has given possibility to make the biggest catalogue of extragalactic sources. The results derived were presented at the 30-th General Assembly of IAU hold in Vienna (Austria) as well as at different international conferences in Lviv, Odesa and Kharkiv.
