  • 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 ...
  • Similarities and differences between heliosphere-geosphere couplings associated with the short and long lived subauroral ionospheric storms: November 2004, F2 region, North East Asia 
    Chelpanov, M.A.; Zolotukhina, N.A. (Advances in Astronomy and Space Physics, 2012)
    We analysed ground and in situ data collected on 9-10 November 2004 during the first day of the long-lived ionospheric storm which consequences were observed in the ionosphere till 13 November and compared the results with ...
  • 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 ...
  • 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 ...
  • Spectroscopic families among diffuse interstellar bands 
    Wszołek, B. (Advances in Astronomy and Space Physics, 2012)
    The inability to identify carriers of the diffuse interstellar bands (DIBs) is one of the longest standing problems in astronomy and astrochemistry. It is debated whether these carriers arise from dust or the gas component ...
  • The distribution of dark matter and intracluster gas in galaxy clusters 
    Babyk, Iu.; Melnyk, O.; Elyiv, A. (Advances in Astronomy and Space Physics, 2012)
    We present the temperature radial profiles of intracluster gas, and the radial profiles of density and mass for dark matter and intracluster gas for five galaxy clusters: Abell 1413, Abell 1204, Abell 2744, Abell 223 and ...
  • The shape and the size of the Universe according to the Poincaré dodecahedral space hypothesis 
    Kazimierczak, T.A. (Advances in Astronomy and Space Physics, 2012)
    One of the best models of the Universe is the Poincaré Dodecahedral Space (PDS) model, which has the best fit to the data of the cosmic microwave background (CMB) sky maps from the Wilkinson Microwave Anisotropy Probe. The ...
  • Trapped fast MGD waves in dayside magnetosphere 
    Voshchepynets, A.; Agapitov, O. (Advances in Astronomy and Space Physics, 2012)
