  • Safonov, B.S. (Advances in Astronomy and Space Physics, 2011)
    Lucky imaging is a method allowing to achieve difiraction resolution on a moderate ground-based telescopes with the cost of magnitude limitation. To adequately evaluate capabilities of this technique for a given place (Mt. ...
  • 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 ...
  • 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, ...
  • 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 ...
  • 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 ...
  • Drazkowska, J.; Hanasz, M.; Kowalik, K. (Advances in Astronomy and Space Physics, 2011)
    Piernik is a multi-fluid grid magnetohydrodynamic code based on the Relaxing Total Variation Diminishing conservative scheme. The original code has been extended by addition of the dust described within the particle ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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. ...
  • 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 ...
  • Chiruta, C. (Advances in Astronomy and Space Physics, 2011)
    We present the model of the photogravitational field proposed by the romanian mathematician Constantin Popovici, basic equations. We give the variation of orbital energy in the photogravitational two bodies problem and ...
  • 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 ...
  • Bykowski, W.; Maciejewski, G. (Advances in Astronomy and Space Physics, 2011)
    The transit monitoring is one of well-known methods for discovering and observing new extrasolar planets. Among various advantages, this way of searching other worlds does not require complex and expensive equipment - it ...
  • Kostogryz, N.M. (Advances in Astronomy and Space Physics, 2011)
    In this work, the vertical cloud distribution in the Uranian atmosphere is investigated. We used the method of determinination of the deviation scope of the real atmosphere from homogeneity conditions. The idea of this ...
