  • CCD VRI photometry of the old open cluster NGC 7142 
    Punanova, A.F.; Loktin, A.V.; Krushinsky, V.V.; Popov, A.A. (Advances in Astronomy and Space Physics, 2012)
    Photometry of 2194 stars in the field of the open cluster NGC 7142 in VRI filters was performed to search variable stars. Eleven probable variable stars were found using robust median statistics. We separated probable ...
  • Smooth time variation spectra as a tool to study line profile variability in spectra of hot stars 
    Sudnik, N.P. (Advances in Astronomy and Space Physics, 2012)
    Line profiles in spectra of almost all OB stars are variable. In many cases the line profile variations are extremely weak (not more than 1% of the continuum level). For detection of such micro line profile variations of ...
  • A word from the Editorial Board 
    Choliy, V. (Advances in Astronomy and Space Physics, 2012)
    This issue of Advances in Astronomy and Space Physics (AASP) represents the new-born "thick" scientific journal. Our aim is to be a broadcast platform for those young scientists who work in astronomy, astrophysics, space ...
  • X-ray selected BL Lacertae objects: catalogue and statistical properties 
    Kapanadze, B.Z. (Advances in Astronomy and Space Physics, 2012)
    The present work focuses on the statistical properties of X-ray selected BL Lacertae objects (XBLs) whose catalogue has been compiled. It consists of 312 sources from different X-ray surveys, unambiguously identified to ...
  • On the non universality of surface density of galaxies 
    Del Popolo, A. (Advances in Astronomy and Space Physics, 2012)
    We studied the correlation between the central surface density of dark matter haloes and the halo core radius of galaxy and galaxy recently studied on a wide range of scales. For this aim we used the secondary infall model, ...
  • Spectral investigations of CM Draconis - new results 
    Kuznetsov, M.K.; Pavlenko, Ya.V.; Jones, H.R.A.; Pinfield, D.J. (Advances in Astronomy and Space Physics, 2012)
    CM Draconis is spectroscopic and eclipsing binary system that consists of two nearly identical M dwarfs. The masses and radii for the components are known with high accuracy. The period of the system is P = 1.268 day. In ...
  • On statistical distributions of wide binary stars 
    Chulkov, D.A.; Trushin, D.I. (Advances in Astronomy and Space Physics, 2012)
    The semi-major axis is a key parameter of binary stellar systems. In order to obtain current semi-major axis distribution we investigated a volume-limited sample of the binaries in solar neighbourhood. Obtained distribution ...
  • On the selection effects in catalogues of binary stars 
    Isaeva, A.A. (Advances in Astronomy and Space Physics, 2012)
    Investigation of physical properties of different kinds of binary stars can provide us with an invaluable information about star formation and evolution. To obtain present-day distributions of binaries along various ...
  • Period changes of the sample of eclipsing binaries with active chromospheres 
    Jableka, D.; Zola, S.; Zakrzewski, B.; Szymanski, T.; Kuzmicz, A.; de Villiers, S.N.; Zejda, M.; Koziel-Wierzbowska, D. (Advances in Astronomy and Space Physics, 2012)
    In this work we present results derived from analysis of the O-C behaviour of ten eclipsing binary systems: AR Lac, CG Cyg, HP Aur, MM Her, RS CVn, RT And, SV Cam, V471 Tau, WW Dra and CF Tuc. It was proved on the basis ...
  • Binary evolution pulsating star - new evolutionary channel to produce RR Lyr-like pulsations 
    Karczmarek, P. (Advances in Astronomy and Space Physics, 2012)
    In 2011 a promising candidate for an RR Lyrae star in an eclipsing binary system was found. Till that time not even one case of RR Lyrae star in a binary system has been known. The pulsator's mass is 0.26 Mꙩ which is not ...
  • In memoriam Siegfried Franck

  • Diffuse interstellar bands towards ο Per and ξ Per 
    Debudej, A.; Kusiak, S.; Ozga, J.; Wszołek, B. (Advances in Astronomy and Space Physics, 2012)
    Spectroscopic characteristics of interstellar matter vary strongly with the direction to the target star. Spectra of oPer and ξ Per contain many prominent and weak diffuse interstellar bands as well as absorption lines of ...
  • Analytical solution of Kompaneets equation 
    Karnaushenko, A.V. (Advances in Astronomy and Space Physics, 2012)
    Analytical solution of Kompaneets equation, describing the movement of shock front from the strong point explosion in the medium with the density changing as the hyperbolic tangent, was obtained. Solution allows to restore ...
  • Criteria for galaxy classification in SDSS 
    Dobrycheva, D.; Melnyk, O. (Advances in Astronomy and Space Physics, 2012)
    We considered the sample of galaxy pairs collected from SDSS DR5. At first we made a morphological classification of approximately 1100 galaxies by visual inspection. As it is known the galaxy morphological types strongly ...
  • X-ray and radio emission of kiloparsec jets at large redshifts 
    Mykhailova, M.S. (Advances in Astronomy and Space Physics, 2012)
    For some jets of core dominant quasars we assumed that the X-ray emission of the nearest to the core knots is produced by the inverse Compton scattering on the quasar emission whereas the X-ray emission of distant knots ...
  • Decametric radio bursts associated with the 13 July 2004 CME event at frequencies 10–30 MHz 
    Boiko, A.I.; Melnik, V.N.; Konovalenko, A.A.; Abranin, E.P.; Dorovskyy, V.V.; Rucker, H.O. (Advances in Astronomy and Space Physics, 2012)
    We report on the observations of solar type IV burst and its precursors on the 13 of July 2004 at frequencies 10 − 30 MHz. The radio telescope UTR-2 observational data compiled from SOHO, WIND, NDA, RHESSI, GOES data were ...
  • Electronic catalogue of the cometary physical characteristics 
    Andrienko, J.; Reshetnyk, V. (Advances in Astronomy and Space Physics, 2012)
    Lack of the new catalogues of the physical characteristics of comets (the last one was published in 1985) was the reason of our work. Vsehsvyatskiy and Andrienko catalogues of the physical characteristics of comets from ...
  • Application of multichannel singular spectrum analysis to geophysical fields and astronomical images 
    Zotov, L.V. (Advances in Astronomy and Space Physics, 2012)
    The results of application of the multichannel singular spectrum analysis (MSSA) to the Earth monitoring data from Jason, GRACE and Aqua satellites are presented. The method helps to divide periodic components, separate ...
  • Two-period variability of the intermediate polar FO Aqr 
    Breus, V.V.; Andronov, I.L.; Hegedus, T.; Dubovsky, P.A.; Kudzej, I. (Advances in Astronomy and Space Physics, 2012)
    We present results of CCD photometric study of the intermediate polar FO Aqr based on observations obtained at the Baja Astronomical Observatory, Hungary, and at the Vihorlat Astronomical Observatory, Slovakia. We analysed ...
