  • The dynamics of the observed solar granulation: spatio-temporal variations of line of sight velocity and thermodynamic parameters 
    Baran, O.A. (Advances in Astronomy and Space Physics, 2014)
    We investigated the dynamics of solar granulation, using the neutral iron line λ ≈ 639.3 nm profiles from highspatial resolution observations around the centre of the solar disc, in the non-perturbed region. We reproduced ...
  • The energy sources of CME acceleration 
    Allawi, H.; Pohjolainen, S. (Advances in Astronomy and Space Physics, 2012)
    We investigate the possibility that during the fast acceleration phase of a coronal mass ejection (CME), a freely propagating shock wave could be launched. We test this hypothesis by calculating the speeds of blast waves ...
  • The firrst spectra for the RX J0440.9+4431 from 2m Terskol telescope

  • The Galactic sky through H.E.S.S. eyes 
    Sushch, I. (Advances in Astronomy and Space Physics, 2015)
    The High Energy Stereosopic System (H.E.S.S.) is an array of five imaging atmospheric Cherenkov telescopes. Since 2003 it has been operating in the configuration of four 12 m telescopes complemented in 2012 by a much bigger ...
  • The influence of extragalactic magnetic fields on the propagation of cosmic rays from Centaurus A 
    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 ...
  • The influence of stellar wind bubbles on the ionizing radiation field in HII regions 
    Koshmak, I.O.; Melekh, B.Ya. (Advances in Astronomy and Space Physics, 2012)
    Stellar wind around starbursts forms cavities filled by hot gas with low density, thermalized by inverse wind shock. Young starbursts can contain the compact cavities inside Hii region. Diffuse ionizing radiation, that ...
  • The luminosity - spectral index dependence of the X-ray bright Seyfert galaxies 
    Sadova, V.A.; Tugay, A.V. (Advances in Astronomy and Space Physics, 2015)
    X-ray luminosities and spectral indices of 97 bright Seyfert 1 (Sy1) galaxies from the XMM-Newton archive are analysed in this article. Distribution of these values is random, so we conclude that the model of emission ...
  • The modernity of the research of Romanian astronomer Constantin Popovici 
    Chiruta, C. (Advances in Astronomy and Space Physics, 2011)
