    In recent years the Joint Laboratory of Atmospheric Optics and Aerosols of Ukraine has been carrying out atmospheric research in cooperation with international program of climate change studies. Our current research is ...
  • 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 ...
  • Malov, I.F.; Nikitina, E.B. (Advances in Astronomy and Space Physics, 2012)
    We analyse homogeneous samples of pulsars at 10 cm and 20 cm and propose to use n, the ratio of the half-width of the radiation cone θ to the minimum angular sight distance from the centre of this cone, to determine the ...
  • Martín, E.L. (Advances in Astronomy and Space Physics, 2012)
    The main aim of the present paper is to give a brief overview of the revolution in exoplanet discoveries which started about two decades ago and the new concepts and perspectives that these observational findings have ...
  • Jableka, D.; Zola, S.; Zakrzewski, B.; Szymanski, T.; Kuzmicz, A.; de Villiers, S.N.; Zejda, M.; Koziel-Wierzbowska, D. (Advances in Astronomy and Space Physics, 2012)
    In this work we present results derived from analysis of the O-C behaviour of ten eclipsing binary systems: AR Lac, CG Cyg, HP Aur, MM Her, RS CVn, RT And, SV Cam, V471 Tau, WW Dra and CF Tuc. It was proved on the basis ...
  • Drozd, K.; Swierczynski, E.; Ragan, E. (Advances in Astronomy and Space Physics, 2012)
    We presented spectroscopic and photometric observations of V407 Cygni obtained during 2006-2011. Our data shows the different activity stages connected with the two components of this symbiotic binary system. Cool giant ...
  • Karczmarek, P. (Advances in Astronomy and Space Physics, 2012)
    In 2011 a promising candidate for an RR Lyrae star in an eclipsing binary system was found. Till that time not even one case of RR Lyrae star in a binary system has been known. The pulsator's mass is 0.26 Mꙩ which is not ...
  • Tanti, K.K.; Roy, J.; Duorah, K. (Advances in Astronomy and Space Physics, 2012)
    In this paper, we present the spectral energy distributions (SEDs) of 40 massive young stellar objects (YSOs), detected from the NIR imaging survey carried out by Varricatt et al. 2010 and estimated their ages and masses. ...
  • 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 ...
  • Frantseva, K.; Kostogryz, N.M.; Yakobchuk, T.M. (Advances in Astronomy and Space Physics, 2012)
    In this paper we present results of linear polarization modelling for HD 189733 in the U filter using the Monte Carlo method. Our simulations are based on the well known effect that linear polarization of a entrosymmetri ...
  • Koshmak, I.O.; Melekh, B.Ya. (Advances in Astronomy and Space Physics, 2012)
    Stellar wind around starbursts forms cavities filled by hot gas with low density, thermalized by inverse wind shock. Young starbursts can contain the compact cavities inside Hii region. Diffuse ionizing radiation, that ...
  • Baran, O.A. (Advances in Astronomy and Space Physics, 2012)
    The exploration of the velocity field of the real solar convection was performed using neutral iron line λ ≈ 639.3 nm profile from the observations with high spatial resolution. The inverse procedure was applied for each ...
  • Allawi, H.; Pohjolainen, S. (Advances in Astronomy and Space Physics, 2012)
    We investigate the possibility that during the fast acceleration phase of a coronal mass ejection (CME), a freely propagating shock wave could be launched. We test this hypothesis by calculating the speeds of blast waves ...
  • 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 ...
  • Glubokova, S.K.; Chashei, I.V.; Tyul'bashev, S.A. (Advances in Astronomy and Space Physics, 2012)
    The method of determining the angular sizes of compact radio sources and parameters of the plasma turbulence using temporal scintillation power spectra is described and tested. The observations were carried out with the ...
  • Shubina, O.; Korsun, P.; Ivashchenko, Yu. (Advances in Astronomy and Space Physics, 2012)
    We analysed the spectroscopic data for comet C/2004 Q2 (Machholz), obtained on the Zeiss-600 telescope in Andrushivka Astronomical Observatory on January 29, 2005. The observed spectrum covers a wavelength range 3600-9200 ...
  • Breuillard, H.; Mendzhul, D.I.; Agapitov, O.V. (Advances in Astronomy and Space Physics, 2012)
    The non-ducted propagation characteristics of the VLF waves in the inner magnetosphere were studied with respect to their frequency, source localization, and initial polar angle between the wave-normal and the background ...
  • Zaitsev, S.V.; Kiselev, N.N.; Rosenbush, V.K.; Velichko, F.P.; Kolesnikov, S.V.; Antonyuk, K.A.; Psarev, V.N. (Advances in Astronomy and Space Physics, 2012)
    We present results of the new polarimetric observations of the Galilean satellites Io, Ganymede, Europe, and Callisto carried out on October 21 - November 1, 2011. We used 1.25m telescope equipped with the UBVRI double ...
  • Lacatus, D.A.; Paraschiv, A.R.; Tesileanu, O. (Advances in Astronomy and Space Physics, 2012)
    Peculiar morphologies have been observed among extragalactic radio sources, which present important sideways features that are yet to be explained. After obtaining the region in the parameter space for which the intended ...
  • Alexandrov, A.N.; Koval, S.M.; Zhdanov, V.I. (Advances in Astronomy and Space Physics, 2012)
    We study approximate solutions of the gravitational lens equation and corresponding lens magnification factor near the critical point. This consideration is based on the Taylor expansion of the lens potential in powers of ...
