  • Bright features in the solar photosphere 
    Kostik, R.I.; Khomenko, E.V. (Кинематика и физика небесных тел, 2005)
    We report thermodynamical properties of so-called “thermal plume” observed near the solar disc centre in 2001. The spectral observations of two iron lines analysed were obtained with the use of the Vacuum Tower Telescope ...

    The angular velocities of chromosphere and photosphere are calculated for 1987–1990 on the basis of heliographic coordinates of the chromospheric flares and sunspots (Solar Geophysical Data). The time resolution accepted ...
  • Evolution of large-scale magnetic fields in the Sun 
    Brayko, P.G. (Кинематика и физика небесных тел, 2005)
    A scenario of evolution of the large-scale magnetic fields in the Sun is proposed. The analysed models of the Sun allow one to accept the shearing of the poloidal field by differential rotation, helical turbulence and also ...

    Some results of analysis of sunspot magnetic fields, including data from published papers (1000 measurements performed at the Mount Wilson National Observatory during 1924–1956) and data from various databases (20 000 ...
  • Large-scale magnetic fields of Sun-heliosphere magnetic system 
    Leiko, U.M. (Кинематика и физика небесных тел, 2005)
    Some results of investigations of solar and interplanetary magnetic fields are presented. The time series of the solar background magnetic field (SBMF) of ±20 degree for 1904–2000, solar mean magnetic field (SMMF) for ...
  • Line-of-sight velocities in a flaring active region 
    Kondrashova, N. (Кинематика и физика небесных тел, 2005)
    Some spectra of a flaring active region were derived with the solar horizontal telescope ATsU-26 at the Terskol Observatory. Some properties of the photospheric velocity field of a bright plage are studied. The measurements ...
  • Line profiles and magnetic fields in the exclusively powerful solar flare of October 28, 2003: preliminary results 
    Lozitsky, V.G.; Lozitska, N.I. (Кинематика и физика небесных тел, 2005)
    We investigate the X17.2/4B solar flare of October 28, 2003 which has been occupying the third place among X-ray fluxes since 1975. The echelle Zeeman spectrograms obtained at the Kyiv University Astronomical Observatory ...
  • Magnetic fields and thermodynamical conditions in the M6.4/3N solar flare on July 19, 2000 
    Kurochka, E.V.; Lozitsky, V.G. (Кинематика и физика небесных тел, 2005)
    We present the semi-empirical model of a powerful solar flare on July 19, 2000 based on spectral observations in the Fe I, Fe II, Cr I, and Ti II lines. Our calculations show the existence of a very narrow (≤ 100 km) and ...
  • Negative magnetic buoyancy and formation of a sunspot belt 
    Kryvodubskyj, V.N. (Кинематика и физика небесных тел, 2005)
    Magnetic buoyancy constrains the magnitude of toroidal field excited by the Ω-effect near the bottom of the solar convection zone (SCZ). Therefore, we examined two negative magnetic buoyancy effects: i) macroscopic turbulent ...

    Gopasyuk, O.S.; Gopasyuk, S.I. (Кинематика и физика небесных тел, 2005)
    The analysis of observed velocity fields in sunspots shows that the plasma motions above a sunspot umbra do not agree with the equation of continuity. We assumed that in the temperature minimum region above a sunspot umbra ...
