  • On the question of detecting granulation signal in CoRoT light curves of A and B stars 
    Ghazaryan, S. (Advances in Astronomy and Space Physics, 2013)
    We applied the procedure written by us to HgMn targets observed both through CoRoT astero and exo channels to check its usefulness for search of possible existence of solar-type granulation signature in their power spectrum. ...
  • Abundance determinations in extragalactic HII regions 
    Pilyugin, L.S. (Advances in Astronomy and Space Physics, 2013)
    The abundance determinations in extragalactic H װ regions are reviewed. The discussion is mainly focused on the different variants of the strong line method (calibrations). However, we do not list and consider in details ...
  • MgH lines in the spectrum of Arcturus 
    Kushniruk, I.O.; Pavlenko, Ya.V.; Kaminskiy, B.M. (Advances in Astronomy and Space Physics, 2013)
    The synthetic spectra of MgH lines were computed for the grid of the model atmospheres and compared with the observed spectrum of Arcturus. The parameters of the atmosphere of Arcturus for log g = 1.5 and Tₑff = 4300K were ...
  • Aerosol Microtops II sunphotometer observations over Ukraine 
    Bovchaliuk, V.; Bovchaliuk, A.; Milinevsky, G.; Danylevsky, V.; Sosonkin, M.; Goloub, Ph. (Advances in Astronomy and Space Physics, 2013)
    Atmospheric aerosols and their impact on climate study are based on measurements by networks of ground-based instruments, satellite sensors, and measurements on portable sunphotometers. This paper presents the preliminary ...
  • Magnetospheric ULF waves driven by external sources 
    Agapitov, O.V.; Cheremnykh, O.K. (Advances in Astronomy and Space Physics, 2013)
    The multi-spacecraft missions (Cluster and THEMIS) observations allowed to collect large data base for Ultra Low Frequency (ULF) waves properties, their localization, and sources. Here we focused mainly on these recent ...
  • Using THELI pipeline in order to reduce Abell 226 multi-band optical images 
    Joveini, R.; Sotoudeh, S.; Roozrokh, A.; Taheri, M. (Advances in Astronomy and Space Physics, 2013)
    In this paper we review THELI (Erben & Schrimer, 2005), an image processing pipeline developed to reduce multipointing optical images taken by mosaic CCD cameras. This pipeline works on raw images by removing several ...
  • Vortex and ULF wave structures in the plasma sheet of the Earth magnetosphere 
    Saliuk, D.A.; Agapitov, O.V. (Advances in Astronomy and Space Physics, 2013)
    We studied the ULF wave packet propagation in the Earth plasma sheet making use of the magnetic field measurements from FGM detector and plasma properties from CORRAL detector aboard the Interball-Tail spacecraft. The MHD ...
  • 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 ...
  • 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 ...
  • Photometric observations of Epsilon Aurigae during the eclipse of 2009-2011 
    Iłkiewicz, K.; Wychudzki, P.; Gałan, C.; Gładkowski, M.; Dobierski, P.; Karska, A.; Więcek, M.; Tomov, T.; Mikołajewski, M. (Advances in Astronomy and Space Physics, 2013)
    Epsilon Aurigae is a bright binary system, in which an F0 supergiant is eclipsed by a dark disk around the companion, every 27.1 years. Although the star has been observed and studied for nearly two centuries, it remains ...
  • Nonthermal emission model of isolated X-ray pulsar RX J0420.0-5022 
    Chkheidze, N.; Babyk, Iu. (Advances in Astronomy and Space Physics, 2013)
    In this paper, an alternative theoretical interpretation to the generally assumed thermal emission models of the observed X-ray spectrum of isolated pulsar RX J0420.0-5022 is presented. It is well-known that at a pulsar ...
  • Telescope inaccuracy model based upon satellite laser ranging data 
    Zhaborovskyy, V.P.; Pap, V.O.; Medvedsky, M.M.; Choliy, V.Ya. (Advances in Astronomy and Space Physics, 2013)

  • Central black holes in giant radio quasars 
    Kuźmicz, A.; Jamrozy, M. (Advances in Astronomy and Space Physics, 2013)
    We analysed optical properties of giant radio quasars (with radio structures larger than 0.7 Mpc). To this day it is unclear why only a small fraction of radio sources attain such large sizes. There are a number of hypotheses ...
  • The discrete dipole approximation code DDscat.C++: features, limitations and plans 
    Choliy, V.Ya. (Advances in Astronomy and Space Physics, 2013)
