  • 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 ...
  • Ammonia molecule and its applications in astrophysics 
    Polinovskyi, G.; Pavlenko, Ya.V.; Tennyson, J.; Yurchenko, S.N.; Barber, R.J. (Advances in Astronomy and Space Physics, 2012)
    Recently a new ammonia line list BYTe was reported comprising more than 1.1 billion transitions and designed for temperatures up to 1500 K. In this study we present an application of this line list for modelling spectra ...
  • Determination of atomic abundances of solar-type stars 
    Malygin, M.G.; Pavlenko, Ya.V.; Jenkins, J.S.; Jones, H.R.A.; Ivanyuk, O.M.; Pinfield, D.J. (Advances in Astronomy and Space Physics, 2012)
    We discuss the results of abundance determinations of the solar-type stars HD 1835 and HD 10700 using our new procedure. This procedure has the advantage of automated pipeline usage for large amounts of spectroscopic data, ...
  • MgH lines in the spectrum of Arcturus 
    Kushniruk, I.O.; Pavlenko, Ya.V.; Kaminskiy, B.M. (Advances in Astronomy and Space Physics, 2013)
    The synthetic spectra of MgH lines were computed for the grid of the model atmospheres and compared with the observed spectrum of Arcturus. The parameters of the atmosphere of Arcturus for log g = 1.5 and Tₑff = 4300K were ...
  • Spectral investigations of CM Draconis - new results 
    Kuznetsov, M.K.; Pavlenko, Ya.V.; Jones, H.R.A.; Pinfield, D.J. (Advances in Astronomy and Space Physics, 2012)
    CM Draconis is spectroscopic and eclipsing binary system that consists of two nearly identical M dwarfs. The masses and radii for the components are known with high accuracy. The period of the system is P = 1.268 day. In ...
  • Surface gravity and effective temperature of the K5 subdwarf G 224-58 A and Arcturus from the fits to Ti and MgH lines 
    Kushniruk, I.O.; Pavlenko, Ya.V.; Gálvez-Ortiz, M.C.; Zhang, Z.H. (Advances in Astronomy and Space Physics, 2016)
    We discuss here the results obtained in the determination of effective temperatures and metallicities of late-type stars. We provide the abundances of MgH, Ti ı and Ti װ, with a list of selected lines, for the red giant ...
