V., Registration Date 01-03-2010 Organization Main Astronomical Observatory popup.description2 A study of populations and distribution of the dark matter in galaxy' halo, galaxy groups (4-10 members) from the Local Supercluster and other samples. At the first time the mass-to luminosity relations were obtained for the poor galaxy groups which give the estimations for the dark matter evolution. The chemical evolution of dwarf galaxy Fornax was investigated. It was returned to the distribution of stars designations for the galaxies in the Fornax scenario, mergers and monolithic evolution. Evolution of fragments took place without metabolism with the environment. This means that systems similar to Fornax, can not be "bricks" from which were formed more massive galaxies. Probably played a role in the merging galaxy formation. The observed metallicity function of this galaxy is better reproduced in the terms of merging than monolit scenario of evolution. The analysis of optical (filter b) and X-ray (2 - 10 keV) brightness curves for the Active Galaxy Nuclei NGC 5548, NGC 7469, NGC 3227, NGC 4051, NGC 4151, Mrk 509, Mrk 79, Akn 564 was conducted. A high correlation between changes in brightness in optical and X-ray ranges and time delays estimations of these short-periodical changes for NGC 5548 and NGC 7469 allows to conclude about the scenario of the Compton over-radiation mechanism due to the accretion on the central black holes in these AGNs. In order to improve our knowledge of carbon stars, we carried out calculations of the energy distribution in the spectrum of C-star WX Cyg in the optical range of 4000-7000, with a view to verifying the list of new models of atmospheres for C-stars. Model atmospheres for C-stars calculated in the classical approximations. Product Description popup.authors Берцик П.П. Вавілова І.Б. Велесь О.А. Виноградов С.Б. Гусєва Н.Г. Елієв А.А. Жиляєв Б. Ю.
