  • Allawi, H.; Al-Ramdhan, W.; Al-Sawad, A. (Advances in Astronomy and Space Physics, 2011)
    We analyzed 25 solar energetic particle events, with energies ∼ 1 − 100 MeV, observed with ERNE instrument onboard Solar and Heliospheric Observatory (SOHO) and found that all of the solar energetic particlse were associated ...
  • Saliuk, D.; Agapitov, O. (Advances in Astronomy and Space Physics, 2011)
    We present some results of the study of nonlinear vortex structures in the Earth's atmosphere known as blocking-anticyclones. It is shown that synoptic-scale structure can be considered in the geostrophic approximation in ...
  • Dobreva, P.S.; Kartalev, M.D. (Advances in Astronomy and Space Physics, 2011)
    We present a new model of the magnetospheric magnetic field. Using the finite element method, ChapmanFerraro problem is solved numerically in the considered approach. The whole magnetic field is a sum of: the dipole field, ...
  • Szczesniak, M.; Szczesniak, R.; Durajsk, A.P.; Jarosik, M.W. (Advances in Astronomy and Space Physics, 2011)
    The modernization of the KLAUDIA radiotelescope, used for the detection of the Earth ionosphere's secondary radiation at 40 kHz±200 Hz waves, is presented in the paper. In particular, the scope of the Very Low Frequency ...
  • Shaldenkova, E.S. (Advances in Astronomy and Space Physics, 2011)
    We consider the new method for atomic hydrogen deficiency estimations. The main idea is to use the empirical relation between total HI mass and specific angular momentum of the disk for isolated galaxies. The method was ...
  • Lacatus, D.A.; Badea, M.; Paraschiv, A.R.; Tesileanu, O. (Advances in Astronomy and Space Physics, 2011)
    Among the extragalactic radio sources there are objects with unusual morphologies. We investigated the possibility that the propagation of jets in a stratified distribution of density may produce such effects. A numerical ...
  • Podorvanyuk, N.Yu.; Vitrishchak, V.M.; Pashchenko, I.N.; Gabuzda, D.C. (Advances in Astronomy and Space Physics, 2011)
    We present the first preliminary evidence of difference in the circular polarized emission between quasars and BL Lacs. BL Lac objects seem to lack the sources with high circular polarization degrees. It cannot be due to ...
  • Vitrishchak, V.M.; Pashchenko, I.N.; Gabuzda, D.C. (Advances in Astronomy and Space Physics, 2011)
    Faraday effects possibly plays the major role in generation of circular polarization observed on Very Long Base Interferometry scales. Multi-frequency circular polarization measurementrs can become the desired breakthrough ...
  • Pahshchenko, I.N.; Pilipenko, S.V.; Vitrishchak, V.M. (Advances in Astronomy and Space Physics, 2011)
    From spectroscopic point of view Seyfert galaxies (as other Active Galactic Nuclei - AGN) basically are subdivided into two types: with and without broad permitted emission lines in their optical spectra (so called type I ...
  • Mykhailova, M.S.; Kontorovich, V.M. (Advances in Astronomy and Space Physics, 2011)
    In this paper the X-ray emission spectrum from the nearest to the quasar 3C 273 inner jet knot A was investigated by the kinetic equation method. It is shown that the inverse Compton scattering of the quasar radio emission ...
  • Malygin, M.G.; Iakubovskyi, D.A. (Advances in Astronomy and Space Physics, 2011)
    In this work, we perform the detailed analysis of absorption features in spectra of magnetar candidates observed by XMM-Newton satellite. No significant line-like feature has been found. This negative result may indicate ...
  • Kobzar, O.; Hnatyk, B.; Marchenko, V.; Bogdan, T. (Advances in Astronomy and Space Physics, 2011)
    Propagation of different chemical composition ultrahigh energy cosmic rays in the galactic magnetic fields was simulated. The simulation for the ultra high energy events, registered by the AUGER observatory in the sky ...
  • Sushchov, O.; Kobzar, O.; Hnatyk, B.; Marchenko, V.; Bogdan, T. (Advances in Astronomy and Space Physics, 2011)
    The motion of different chemical composition of ultra high energy cosmic rays in the galactic magnetic fields with taking into account the extragalactic magnetic field was considered. The ultra high energy events registered ...
  • Baran, O.A. (Advances in Astronomy and Space Physics, 2011)
    The temperature and velocity field within granular cells has been studied by solving the nonequilibrium inverse radiative transfer problem using neutral iron line λ ≈ 523.4 nm profiles. The results are the following: the ...
  • Nasonov, D.S. (Advances in Astronomy and Space Physics, 2011)
    Infrared source IRAS 01005+7910 is identified with an 11-mag peculiar star which has been previously found to be a post asymptotic giant branch star of early spectral type. There is significant spectral variability detected ...
  • Nikitina, E.B.; Malov, I.F. (Advances in Astronomy and Space Physics, 2011)
    There are some known theoretical models used for investigations of pulsars at present. One of the most important parameters for the check of existing pulsar models is the angle β between an axis of an emission cone (a ...
  • Simon, A.; Bondar, A.V.; Reshetnyk, V.M. (Advances in Astronomy and Space Physics, 2011)
    We present the rst results on the spectra of Be/X-ray binary RX J0440.9+4431 obtained with the 2m Ritchey-Chretein-Coude telescope with Cassegrain Multi Mode Spectrograph (CMMS) (with R = 14000) at Terskol observatory. ...
  • Pakhomov, Yu.V.; Chugai, N.N.; Iyudin, A.F. (Advances in Astronomy and Space Physics, 2011)
    We present the method for study of the characteristics of the supernova remnants using their absorption properties. The background radiation sources are several stars with wide range of distances. Main task is accurate ...
  • Saburova, A.S. (Advances in Astronomy and Space Physics, 2011)
    On the example of four low surface brightness galaxies we demonstrate that the mass-to-light ratio of their disks may be found from the condition of marginal gravitational stability. In this case their surface densities ...
  • Rozenkiewicz, A.; Gozdziewski, K.; Migaszewski, C. (Advances in Astronomy and Space Physics, 2011)
    More than 450 extrasolar planets are known to date. To detect these intriguing objects many photometric and radial velocity surveys are in progress. We developed the Keplerian FITting code, to model published and available ...
