  • Absorption burst in the solar sporadic radio emission at 10−30 MHz frequencies 
    Konovalenko, A.A.; Stanislavsky, A.A.; Abranin, E.P.; Dorovsky, V.V.; Mel'nik, V.N. (Кинематика и физика небесных тел, 2005)
    We report the results of UTR-2 radio telescope observations of an absorption burst at the decameter range. This event is associated with two consecutive M-class flares and happened after the second M-flare. The latter flare ...
  • 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 ...
  • Decameter pulsar/transient survey of northen sky. First results 
    Vasylieva, I.Y.; Zakharenko, V.V.; Konovalenko, A.A.; Zarka, P.; Ulyanov, O.M.; Shevtsova, A.I.; Skoryk, A.O. (Радиофизика и радиоастрономия, 2014)
    The decameter pulsar/transient survey is now being made using the UTR-2 radio telescope. The survey strategy and parameters, equipment characteristics, data processing algorithms as well as preliminary results are described. ...
  • 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 ...
  • Frequency drift rates of powerful decameter Type III bursts 
    Boiko, A.I.; Mel'nik, V.N.; Konovalenko, A.A.; Rucker, H.O.; Abranin, E.P.; Dorovskyy, V.V.; Lecacheux, A. (Advances in Astronomy and Space Physics, 2011)
    We report on the observations of powerful (fluxes are larger than 10⁻¹⁹ W m⁻² Hz⁻¹) solar Type III bursts at frequencies 10 − 30 MHz. Recordings of 163 bursts, observed in July 2002 and of 231 bursts observed in August ...
  • Low-Frequency Carbon Recombination Lines 
    Konovalenko, A.A.; Stepkin, S.V.; Shalunov, D.V. (Радиофизика и радиоастрономия, 2001)
    The low-frequency carbon recombination lines (with wavelengths up to twenty five and even more meters) became important means of the low-density interstellar plasma diagnostics. An impressive amount of astrophysical ...
  • New decameter radiopolarimeter URAN-2 
    Brazhenko, A.I.; Bulatsen, V.G.; Vashchishin, R.V.; Frantsuzenko, A.V.; Konovalenko, A.A.; Falkovich, I.S.; Abranin, E.P.; Ulyanov, O.M.; Zakharenko, V.V.; Lecacheux, A.; Rucker, H. (Кинематика и физика небесных тел, 2005)
    The description of the new decameter radiopolarimeter is submitted. It is created based on the phased array URAN-2, which is the greatest decameter array in the world after UTR-2, having the effective area about 30 000 m2, ...
  • New methods and equipment of decametric radio astronomy for continuum observation at the UTR-2 radio telescope 
    Sidorchuk, K.M.; Konovalenko, A.A.; Rucker, H.O.; Lecacheux, A.; Denis, L.; Sidorchuk, M.A.; Rashkovsky, S.L.; Dorovsky, V.V.; Zakharenko, V.V. (Кинематика и физика небесных тел, 2005)
    At present time the modernization of the giant decametric radio telescope UTR-2 is under way. New back-end facilities and methods which open up new possibilities for radio astronomical observations are developed. Some ...
  • Search of the radio emission from flare stars at decameter wavelengths 
    Boiko, A.I.; Konovalenko, A.A.; Koliadin, V.L.; Melnik, V.N. (Advances in Astronomy and Space Physics, 2012)
    Observations of the two M-dwarf flare stars (AD Leonis and EV Lacertae), which were carried out with the radio telescope UTR-2 (Kharkiv, Ukraine) in the range of 16.5 − 33 MHz, are presented. 167 events of radio emission ...
