  • On the extension of Helmert transform 
    Choliy, V.Ya. (Advances in Astronomy and Space Physics, 2014)
    The article deals with the method of comparison of the coordinate systems used by two quite different scientific disciplines: stellar astronomy and the geodesy. Geodesic Helmert transform is analysed along with a series ...
  • Abundances in the atmosphere of the metal-rich planet-host star HD 77338 
    Kushniruk, I.O.; Pavlenko, Ya.V.; Jenkins, J.S.; Jones, H.R.A. (Advances in Astronomy and Space Physics, 2014)
    Abundances of Fe, Si, Ni, Ti, Na, Mg, Cu, Zn, Mn, Cr and Ca in the atmosphere of the K-dwarf HD 77338 are determined and discussed. HD 77338 hosts a hot Uranus-like planet and is currently the most metal-rich single star ...
  • "Inter-Longitude Astronomy" project: long period variable stars 
    Andronov, I.L.; Marsakova, V.I.; Kudashkina, L.S.; Chinarova, L.L. (Advances in Astronomy and Space Physics, 2014)
    This article contains the highlights of complex studies of long-period variable stars such as Miras: semiregular, symbiotic (particularly, pulsating symbiotic), as well as RV Tauri-type stars. In the course of these studies, ...
  • New emission line at ~3.5 keV - observational status, connection with radiatively decaying dark matter and directions for future studies 
    Iakubovskyi, D.A. (Advances in Astronomy and Space Physics, 2014)
    Recent works of Bulbul et al. (2014) and Boyarsky et al. (2014), claiming the detection of the extra emission line with energy ∼3.5 keV in X-ray spectra of certain clusters of galaxies and nearby Andromeda galaxy, have ...
  • Low-resolution spectroscopy of the chromospherically active stars 61 Cyg AB with small telescopes 
    Pokhvala, S.M.; Zhilyaev, B.E.; Reshetnyk, V.M.; Shavlovskij, V.I. (Advances in Astronomy and Space Physics, 2014)
    We carried out high-speed low-resolution spectroscopy of two stars, 61 Cyg A and B with small telescopes. They are known as chromospherically active stars of the K5V (A) and K7V (B) spectral types. These two stars are ...
  • Photometric variability of the 1H1936+541 star in 2008-2014 
    Simon, A.O.; Vasylenko, V.V.; Metlova, N.V. (Advances in Astronomy and Space Physics, 2014)
    We report the results of observations of the Be/X-ray binary system 1H1936+541. All of the data were obtained on the base of Lisnyky observational station (Astronomical Observatory of the Taras Shevchenko National University ...
  • The dynamics of the observed solar granulation: spatio-temporal variations of line of sight velocity and thermodynamic parameters 
    Baran, O.A. (Advances in Astronomy and Space Physics, 2014)
    We investigated the dynamics of solar granulation, using the neutral iron line λ ≈ 639.3 nm profiles from highspatial resolution observations around the centre of the solar disc, in the non-perturbed region. We reproduced ...
  • Photometry of distant active comet C/2010 S1 (LINEAR) 
    Shubina, O.; Kulyk, I.; Korsun, P.; Romanjuk, Ya. (Advances in Astronomy and Space Physics, 2014)
    We present the results of photometric observations of a dynamically new comet C/2010 S1 (LINEAR), conducted on June 18, 2012. The comet demonstrated a considerable level of physical activity at a heliocentric distance of ...
  • Extragalactic filament detection with a layer smoothing method 
    Tugay, A.V. (Advances in Astronomy and Space Physics, 2014)
    Filaments are clearly visible in galaxy distributions, but they are dificult to detect by computer algorithms. Most methods of filament detection can be used only with numerical simulations of a large-scale structure. New ...
  • 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, ...
  • 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 ...
  • Earth's pole coordinates determined from Lageos-1/2 laser ranging 
    Zhaborovskyy, V.P.; Choliy, V.Ya. (Advances in Astronomy and Space Physics, 2014)
    The Earth's pole coordinates, obtained from satellite laser ranging data of Lageos-1 and Lageos-2 are presented. The procedure, used models and algorithms are described. Results are compared with similar series from IERS database.
