  • 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 ...
  • Dynamics of dark energy in collapsing halo of dark matter 
    Tsizh, M.; Novosyadlyj, B. (Advances in Astronomy and Space Physics, 2015)
    We investigate the non-linear evolution of spherical density and velocity perturbations of dark matter and dark energy in the expanding Universe. For this we have used the conservation and Einstein equations to describe ...
  • Fast radio bursts as electromagnetic radiation from cusps on superconducting cosmic strings 
    Zadorozhna, L.V. (Advances in Astronomy and Space Physics, 2015)
    Cosmic strings are topological defects, relicts of the early Universe, which can be formed during phase transitions of fields with spontaneous broken symmetry. There also exists a special class of cosmic strings - ...
  • Geometry of highly inclined protoplanetary disks 
    Zakhozhay, O.V.; del Burgo, C.; Zakhozhay, V.A. (Advances in Astronomy and Space Physics, 2015)
    We present a geometric model for the modelling of spectral energy distribution of inclined protoplanetary disks. We investigate peculiarities in the geometry of nearly edge-on disks with an inner hole and a central object. ...
  • High-frequency variations of hydrogen spectral lines in the B3V star η UMa 
    Pokhvala, S.M. (Advances in Astronomy and Space Physics, 2015)
    We reported the detection of high-frequency variations in the hydrogen Balmer lines in the hot star η UMa of spectral class B3V. Spectral observations of η UMa were carried out with slitless spectrograph (R ∼ 100) installed ...
  • Nitrogen abundance in the Blue Compact Dwarf galaxies from SDSS 
    Vovk, K.B. (Advances in Astronomy and Space Physics, 2015)
    We examined all of the galaxies in the Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7) to select those with a dete ted [O ΙΙΙ ] λ4363 emission line, whih allows to derive electron temperatures in H װ regions and element ...
  • Polarimetry of Saturnian satellite Enceladus 
    Zaitsev, S.V.; Kiselev, N.N.; Rosenbush, V.K.; Kolesnikov, S.V.; Shakhovskoy, D.N. (Advances in Astronomy and Space Physics, 2015)
    We present results of polarimetric observations of Saturn's moon Enceladus carried out from April 14, 2010 to April 13, 2013 in WR spectral band (550-750 nm). We used 2.6-m telescope equipped with a one-channel photoelectric ...
  • Project VeSElkA: Vertical Stratification of Element Abundances in CP stars 
    Khalack, V.R.; LeBlanc, F. (Advances in Astronomy and Space Physics, 2015)
    A new research project on spectral analysis which aims to characterize the vertical stratification of element abundances in stellar atmospheres of chemically peculiar (CP) stars, is discussed in detail. Some results on ...
  • Remote sensing of aerosol in the terrestrial atmosphere from space: new missions 
    Milinevsky, G.; Yatskiv, Ya.; Degtyaryov, O.; Syniavskyi, I.; Ivanov, Yu.; Bovchaliuk, A.; Mishchenko, M.; Danylevsky, V.; Sosonkin, M.; Bovchaliuk, V. (Advances in Astronomy and Space Physics, 2015)
    The distribution and properties of atmospheric aerosols on a global scale are not well known in terms of determination of their effects on climate. This mostly is due to extreme variability of aerosol concentrations, ...
  • Results of 5-year photometric monitoring of the intermediate polar V2306 Cygni: correction of the orbital period and evidence of 2-day periodicity 
    Breus, V.; Petrík, K.; Zoła, S.; Baransky, A.; Hegedus, T. (Advances in Astronomy and Space Physics, 2015)
    We present the results of 6 years of photometric monitoring of the magnetic cataclysmic variable V2306 Cygni (formerly known as 1WGA J1958.2+3232) obtained at collaborating observatories. Using (O-C) analysis we tried to ...
