  • Damping of magnetospheric toroidal Alfvén eigenmodes due to phase mixing 
    Cheremnykh, S.O.; Parnowski, A.S. (Advances in Astronomy and Space Physics, 2013)
    We demonstrate that toroidal shear Alfvén eigenmodes in dipolar magnetostatic plasma equilibrium are subject to damping due to phase mixing. This result is of particular interest for the investigation of Pc5-6 geomagnetic ...

    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, ...
  • Determination of the reference frames deflections from optical observations of GNSS satellites 
    Choliy, V.Ya.; Zhaborovskyy, V.P.; Taradiy, V.; Rykhlova, L. (Advances in Astronomy and Space Physics, 2011)
    Optical observations of navigation satellites were carried out at Terskol observatory during 2007-2010 with the aim to determine the deffection angles between GPS and GLONASS dynamical reference frames. There were three ...
  • 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 ...
  • Diffusion processes in the transition layer of the Earth's magnetosphere 
    Prokhorenkov, A.S.; Kozak, L.V.; Lui, A.T.Y.; Gala, I.V. (Advances in Astronomy and Space Physics, 2015)
    Turbulence has a different nature in the interplanetary magnetic field and in the transition region, thus it requires a different type of analysis. The "Cluster 2" satellite mission provides magnetic measurements with a ...
  • Digital version of the CrAO archive of spectral observations of the Sun, carried out with the KG-2 coronagraph 
    Fursiak, Yu.A. (Advances in Astronomy and Space Physics, 2012)
    With the development of computer technology a topical problem to digitize the astronomical data stored on various media, for their preservation and accessibility for further faster and more accurate processing has arisen. ...
  • Distribution of areas of radiation generation at different frequencies in pulsar magnetospheres 
    Malov, I.F.; Nikitina, E.B. (Advances in Astronomy and Space Physics, 2012)
    We analyse homogeneous samples of pulsars at 10 cm and 20 cm and propose to use n, the ratio of the half-width of the radiation cone θ to the minimum angular sight distance from the centre of this cone, to determine the ...
  • Do BL Lacs lack the circular polarization? 
    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 ...
  • Dynamics of dark energy in collapsing halo of dark matter 
    Tsizh, M.; Novosyadlyj, B. (Advances in Astronomy and Space Physics, 2015)
    We investigate the non-linear evolution of spherical density and velocity perturbations of dark matter and dark energy in the expanding Universe. For this we have used the conservation and Einstein equations to describe ...
  • Earth's pole coordinates determined from Lageos-1/2 laser ranging 
    Zhaborovskyy, V.P.; Choliy, V.Ya. (Advances in Astronomy and Space Physics, 2014)
    The Earth's pole coordinates, obtained from satellite laser ranging data of Lageos-1 and Lageos-2 are presented. The procedure, used models and algorithms are described. Results are compared with similar series from IERS database.
  • Ecospheres around binary stars 
    Deka, B. (Advances in Astronomy and Space Physics, 2011)
    Scientific investigations concerning ecospheres of other stars are very important for understanding the posibilities of existence and evolution of extraterrestrial life. In several last years astronomers discovered hundreds ...
  • Effects of equatorial chorus wave normal azimuthal distribution on wave propagation 
    Breuillard, H.; Mendzhul, D.I.; Agapitov, O.V. (Advances in Astronomy and Space Physics, 2012)

  • Electromagnetic radiation of superconducting cosmic strings 
    Rogozin, D.A.; Zadorozhna, L.V. (Advances in Astronomy and Space Physics, 2013)
    Cosmic strings are relics of the early Universe which can be formed during the phase transitions of fields with spontaneously broken symmetry in the early Universe. Their existence finds support in modern superstrings ...
  • 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 ...
  • Estimation of the flux tube diameters outside sunspots using Hinode observations. Preliminary results 
    Botygina, O.O.; Gordovskyy, M.Yu.; Lozitsky, V.G. (Advances in Astronomy and Space Physics, 2016)
