The spectrum of close binary system NN Ser is investigated by a models atmospheres method. It is show that the atmosphere near the centrum of a hot spot on surface of red dwarf has powerful chromospheres, arising from heating in Laiman continua. Four

Solar spectrum of Nal lines by method of the nonLTE analysis is investigated. It shown, that in atmosphere of the Sun the Nal is in moderate ”overrecombination”. The analysis of influence of atomic data, models of atmospheres and damping constant

Results of X-ray Novae (XN) optical spectra computation are presented. The continuum and Balmer line are calculated. The model of XN as a self-irradiated accretion disk is used. Local (for given radius) disk atmospheres as model stellar atmospheres,

NonLTE calculations for the Nal and Mgl atoms were performed for model atmospheres of Tef= 4000 - 12000K. logg = 0.0 - 4.5, [NI/H] = 0.5- (-4). Departures from LTE result in strengthening the Nal spectral lines and weakening the Mgl ones. For 8 Nal s

We report the results of the investigations of chemical composition of close binaries which had gone through the stage of common envelope and which are the remnants of planetary nebular cores. High resolution spectra for different phases of orbital p

We performed special test calculations for 2 different sets of atomic data: with data from TOP base database (Seaton M.J.,Zeippen C.J.,Tully .A. et al., 1992), and with set of sections from (Hofsaess D., 1979) to estimate the effect of adopted valu

About 200 echelle spectra, obtained at the 1-m and 6-m telescopes of the Special Astrophysical Observatory (SAO) of the Russian Academy of Sciences (RAS), with high spectral resolution and signal-to-noise ratio, were used to investigate the radial ve
