  • Long-term photopolarimetric variability of DD Ser 
    Belan, S.P.; Shakhovskoy, D.N. (Advances in Astronomy and Space Physics, 2013)
    We present some results of UBVRI-photopolarimetric observations of DD Ser, a poorly studied and understood Ae-star. The long-term component of light variation is detected, with the period of about fifteen years. Variability ...
  • Fast-growing sunspot groups AR1618, AR1619, AR1620, AR1640 and their features 
    Fursiak, Yu.A. (Advances in Astronomy and Space Physics, 2013)
    The paper considers evolutionary features of fast-growing sunspot groups AR1618, AR1619, AR1620, and AR1640. The study consists of the analysis of magnetic fields, movements of the solar atmosphere at different levels, and ...
  • Power spectra of convective motions in the solar photosphere 
    Baran, O.A. (Advances in Astronomy and Space Physics, 2013)
    We reproduced the convective velocity field and the temperature structure of the solar photosphere using neutral iron line λ ≈ 639.3 nm profiles from the observations with high spatial resolution taken around the centre ...
  • Changes in the spectral index of the interplanetary plasma turbulence in the period of low solar activity from observations of strongly scintillating source 3C 298 
    Glubokova, S.K.; Chashei, I.V.; Tyul'bashev, S.A.; Shishov, V.I. (Advances in Astronomy and Space Physics, 2013)
    We present the results of the analysis of temporal power spectra of interplanetary scintillation for the strong radio source 3C 298 observed at 111 MHz with radio telescope BSA LPI in the period near the solar activity ...
  • Application of the full reduction technique for solution of equations with vector form non-linearity 
    Saliuk, D.A. (Advances in Astronomy and Space Physics, 2013)
    We consider making use of the full reduction algorithm for solving the equations with a vector non-linearity. The solutions of such the equations describe the planetary scale non-linear vortex structures of the Earth ...
  • V407 Cyg and RS Oph - comparison of two exotic variables 
    Drozd, K.; Swierczynski, E.; Ragan, E.; Buil, C. (Advances in Astronomy and Space Physics, 2013)
    V407 Cygni and RS Ophiuchi are two similar but unique objects. It can be said that they each belong to an individual type of stars. During their quiet state they seem to be symbiotic stars. However, both stars have previously ...
  • The two accretion states of the polar 1RXS J184542 in 2012 
    Shchurova, A.V.; Pavlenko, E.P.; Malanushenko, V.P. (Advances in Astronomy and Space Physics, 2013)
    We present the photometric investigation of the newly discovered magnetic cataclysmic variable (polar) 1RXS J184542 during four months in 2012. We used the CCD observations in R-band obtained with the 0.5-m ARCSAT telescope ...
  • The spatial variability of PM₂.₅ over Europe using satellite POLDER-3/PARASOL data 
    Bovchaliuk, A. (Advances in Astronomy and Space Physics, 2013)
    The paper presents the results of the monthly mean PM₂.₅ analysis in the period from 2005 to 2013 over the Europe based on the connection between daily fine particle concentrations (PM₂.₅) by surface in-situ measurements ...
  • Observations of Sy2 galaxy NGC 3281 by XMM-Newton and INTEGRAL satellites 
    Vasylenko, A.A.; Fedorova, E.; Zhdanov, V.I. (Advances in Astronomy and Space Physics, 2013)
    We present the results of the analysis of X-ray properties of the Seyfert 2 galaxy NGC 3281, based on the observational data obtained by XMM-Newton and INTEGRAL within the energy ranges 0.2-12 keV and 20-150 keV, respectively. ...
  • Stochastic scattering in Cen A radio lobes 
    Sydorenko, M.V.; Marchenko, V.V.; Sushchov, O.B.; Kobzar, O.O. (Advances in Astronomy and Space Physics, 2013)
    The results of direct numerical modelling of the cosmic ray acceleration in strongly excited turbulence, where quasi-linear theory is non-applicable, are presented. We model turbulent plasma by a set of randomly propagated ...
  • Database of satellite polarimetry 
    Zaitsev, S.V.; Rosenbush, V.K.; Kiselev, N.N. (Advances in Astronomy and Space Physics, 2013)
    We present the electronic database (EAR-SA-COMPIL-3-SATPOL-V1.0, NASA Planetary Data System), involving 2355 published and 105 unpublished results in planetary satellite polarimetry. The database contains 2460 measurements ...
  • Bright X-ray galaxies in SDSS filaments 
    Tugay, A.V. (Advances in Astronomy and Space Physics, 2013)
    Eighteen bright X-ray emitting galaxies were found in nearby filaments within the SDSS region. Basic X-ray spectral parameters were estimated for these galaxies using a power law model with photoelectric absorption. A close ...
  • Explosive evolution of galaxies at high redshifts due to minor mergers 
    Kats, A.V.; Kontorovich, V.M. (Advances in Astronomy and Space Physics, 2013)
    In the case of minor mergers analytical solutions of kinetic Smoluchowski equation with a source that corresponds to separation of galaxies from the general expansion of the universe have been found. The solutions describe ...
  • Optical observations of selected asteroids with measurable Yarkovsky effect 
    Pomazan, A.V.; Maigurova, N.V. (Advances in Astronomy and Space Physics, 2013)
    The results of the observations of 10 asteroids for 2009-2012 and their analysis are presented here. The asteroids were selected based on the available list of asteroids with relatively large deviations from the unperturbed ...
  • On the comparison of fundamental numerical ephemerides 
    Tkachuk, V.V.; Choliy, V.Ya. (Advances in Astronomy and Space Physics, 2013)
    We present the results of our comparison of three main numerical ephemerides (DELE, INPOP, EPM) for the determination of precision and errors of their dynamical coordinate systems. It was shown that all of them have ...
  • Tests of commercial colour CMOS cameras for astronomical applications 
    Pokhvala, S.M.; Reshetnyk, V.M.; Zhilyaev, B.E. (Advances in Astronomy and Space Physics, 2013)
    We present some results of testing commercial colour CMOS cameras for astronomical applications. Colour CMOS sensors allow to perform photometry in three filters simultaneously that gives a great advantage compared with ...
  • 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 ...
