  • Catalogue-atlas of photographic observations along Comet Liller's path 
    Fursiak, Yu.A.; Shlyapnikov, A.A. (Advances in Astronomy and Space Physics, 2012)
    We present the on-line version of the catalogue-atlas of photographic observations along the path of comet Liller (1988a). The comet was observed in the N. D. Kalinenkov Astronomical Observatory (AOK) of the Nikolaev ...

  • Centaurus A as a plausible source of ultra high energy cosmic rays registered by the Pierre Auger Observatory 
    Sushchov, O.B.; Kobzar, O.O.; Hnatyk, B.I.; Marchenko, V.V. (Advances in Astronomy and Space Physics, 2012)
    For ultra high energy cosmic rays events detected by the Pierre Auger Observatory which arrive from the region near Centaurus A the positions of the corresponding sources were calculated for the two chosen galactic magnetic ...
  • 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 ...
  • Chandra observations of ten galaxy clusters 
    Babyk, Iu.; Melnyk, O.; Elyiv, A. (Advances in Astronomy and Space Physics, 2012)
    In the present study the X-ray properties of 10 galaxy clusters (CL0024+17, RXJ1347.5+1145, A223, A521, A611, A697, A907, A1204, A1413 and A2744) are analysed using the archival X-ray data of the Chandra observatory. The ...
  • 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 ...
  • 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)
    Formulae for critical angles and areas that permit to imagine configurations of observed systems and to calculate their spectral energy distributions (SEDs) as dependencies on their geometrical parameters and inclination ...
  • Comparative analysis of decametre 'drift pair' bursts observed in 2002 and 2015 
    Volvach, Ya.S.; Stanislavsky, A.A.; Konovalenko, A.A.; Koval, A.A.; Dorovskyy, V.V. (Advances in Astronomy and Space Physics, 2016)
    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)
