  • 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 ...

  • Centaurus A as a plausible source of ultra high energy cosmic rays registered by the Pierre Auger Observatory 
    Sushchov, O.B.; Kobzar, O.O.; Hnatyk, B.I.; Marchenko, V.V. (Advances in Astronomy and Space Physics, 2012)
    For ultra high energy cosmic rays events detected by the Pierre Auger Observatory which arrive from the region near Centaurus A the positions of the corresponding sources were calculated for the two chosen galactic magnetic ...
  • 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 ...
  • 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 ...
  • Determination of atomic abundances of solar-type stars 
    Malygin, M.G.; Pavlenko, Ya.V.; Jenkins, J.S.; Jones, H.R.A.; Ivanyuk, O.M.; Pinfield, D.J. (Advances in Astronomy and Space Physics, 2012)
    We discuss the results of abundance determinations of the solar-type stars HD 1835 and HD 10700 using our new procedure. This procedure has the advantage of automated pipeline usage for large amounts of spectroscopic data, ...
  • 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 ...
  • 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 ...
  • In memoriam Siegfried Franck 
    Автор відсутній (Advances in Astronomy and Space Physics, 2012)
  • Interstellar spectral features and telluric absorption lines 
    Kuźmicz, A.; Wszołek, B. (Advances in Astronomy and Space Physics, 2012)
    In good quality spectra of stars the weak interstellar absorption lines may be substantially contaminated by telluric lines. Many telluric lines may also simulate interstellar absorptions. To avoid undesirable telluric ...
  • Magnetized Rossby waves in mid-latitude ionosphere F-layer 
    Saliuk, D.A.; Agapitov, O.; Milinevsky, G.P. (Advances in Astronomy and Space Physics, 2012)
    We present the results of study of the ionosphere quasi-periodic perturbations on the basis of the analysis of the critical f0F2 frequency variations. The temporal scales of the perturbations are about 7 days and relative ...
  • MHD waves in the plasma system with dipole magnetic field configuration 
    Cheremnykh, S.O.; Agapitov, O. (Advances in Astronomy and Space Physics, 2012)
    The eigenmode spectrum of the ultra low frequency (ULF) waves in the Earth magnetosphere is discrete and consists of Alfvén and slow magnetosonic modes. Their interaction depends on ionospheric conductivity and the magnetic ...
  • 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 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, ...
  • 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 ...
  • On the structure of pulsar magnetospheres 
    Malov, I.F.; Nikitina, E.B. (Advances in Astronomy and Space Physics, 2012)
    The angles β between rotation and magnetic axes in the radio pulsar magnetospheres can be calculated with several methods. In this paper we present the results of calculations for three samples of radio pulsars at 10, 20 ...
  • Parametric modeling of global TEC fields 
    Prokhorenkov, A.S.; Choliy, V.Ya. (Advances in Astronomy and Space Physics, 2012)
    We applied the autoregressive moving average statistical modelling to analysis and forecasting of the global Total Electron Content maps. Autoregressive moving average is a parametric time series and fields modelling method, ...
  • Pc1-pulsations: the parallel structure in the magnetosphere plasma with the admixture of the heavy ions 
    Mikhailova, O.S.; Klimushkin, D.Yu.; Mager, P.N. (Advances in Astronomy and Space Physics, 2012)
    The paper deals with the parallel structure of ultra-low frequency waves. To obtain the function describing the wave field we use the quasi-perpendicular approximation (k ̝ » k ֽֽ). Different regions of the wave propagation ...
  • Project of program package for exploring of cosmological fractals 
    Lovyagin, N.Yu. (Advances in Astronomy and Space Physics, 2012)
    The value of fractal dimension and inhomogeneity scale of the spatial distribution of galaxies is a widely discussed problem in the modern cosmology. To solve it one should carefully test the reliability of methods of ...
  • Results from the Pierre Auger Observatory 
    Šmída, R. (Advances in Astronomy and Space Physics, 2012)
    The Pierre Auger Observatory is the largest observatory of high-energy cosmic rays. It is located in Argentina and has been taking data since January 2004. Extensive air showers initiated by cosmic rays are measured by the ...
