  • Circular polarization of AGNs on the parsec VLBI scales 
    Vitrishchak, V.M.; Pashchenko, I.N.; Gabuzda, D.C. (Advances in Astronomy and Space Physics, 2011)
    Faraday effects possibly plays the major role in generation of circular polarization observed on Very Long Base Interferometry scales. Multi-frequency circular polarization measurementrs can become the desired breakthrough ...
  • Circumsubstellar disk SED in dependence on system parameters 
    Zakhozhay, O. (Advances in Astronomy and Space Physics, 2012)

    We report about new observations of solar "drift pair" (DP) bursts by means of the UTR-2 radio telescope at frequencies 10-30 MHz. Our experimental data include both "forward" and "reverse" bursts with high frequency and ...
  • Contamination of RR Lyrae stars from Binary Evolution Pulsators 
    Karczmarek, P. (Advances in Astronomy and Space Physics, 2015)
    A Binary Evolution Pulsator (BEP) is a low-mass (0.26Mꙩ ) member of a binary system, which pulsates as a result of a former mass transfer to its companion. The BEP mimics RR Lyrae-type pulsations, but has completely different ...
  • Coronal jet contribution to the slow Solar wind flux: preliminary results 
    Paraschiv, A.R.; Dragomirescu, D.; Stan, L.; Talpeanu, D.C.; Ivan, C.; Radu, S.; Lacatus, D.A.; Mierla, M. (Advances in Astronomy and Space Physics, 2012)
    The solar wind is a continuous flux of charged particles that are ejected from the Sun's atmosphere. The sources of this flux have not been clearly identiffed yet. Coronal jets are proposed as a possible candidate. They ...
  • Creation of 2-5 keV and 5-10 keV sky maps using XMM-Newton data 
    Savchenko, D.O.; Iakubovskyi, D.A. (Advances in Astronomy and Space Physics, 2014)
    Sky maps are powerful visualisation tools for quicklook analysis of extended sources. The latest sky map in soft X-rays (0.1-2.4 keV) has been created in the 1990's using ROSAT data. By analysing publically available data ...
  • Criteria for galaxy classification in SDSS 
    Dobrycheva, D.; Melnyk, O. (Advances in Astronomy and Space Physics, 2012)
    We considered the sample of galaxy pairs collected from SDSS DR5. At first we made a morphological classification of approximately 1100 galaxies by visual inspection. As it is known the galaxy morphological types strongly ...
  • Cyclic Period Changes of β Lyrae-type Eclipsing Variable Stars KR Cyg, V382 Cyg and BX And 
    Tvardovskyi, D.E.; Marsakova, V.I. (Advances in Astronomy and Space Physics, 2015)
    We have studied three binary stellar systems KR Cyg, V382 Cyg and BX And, which are eclipsing variables of the β Lyrae - type. We have studied the phase curves and O-C curves. The forms of their O-C curves are sinusoidal ...
  • 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 ...
  • Dark matter in the Local Group 
    Kudrya, Yu.N.; Tsykaliuk, Iu.Iu. (Advances in Astronomy and Space Physics, 2014)
    The observational properties of galaxies aumulated in the Updated Nearby Galaxy Catalog (UNGC) were used by us to derive an orbital mass of the Milky Way and Andromeda galaxy (M 31) via motions of their 31 and 39 ompanions, ...
  • 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 ...
  • Decametric radio bursts associated with the 13 July 2004 CME event at frequencies 10–30 MHz 
    Boiko, A.I.; Melnik, V.N.; Konovalenko, A.A.; Abranin, E.P.; Dorovskyy, V.V.; Rucker, H.O. (Advances in Astronomy and Space Physics, 2012)
    We report on the observations of solar type IV burst and its precursors on the 13 of July 2004 at frequencies 10 − 30 MHz. The radio telescope UTR-2 observational data compiled from SOHO, WIND, NDA, RHESSI, GOES data were ...

  • 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)

  • 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)
