  • Krelowski, J.; Musaev, F.A.; Galazutdinov, G.A. (Кинематика и физика небесных тел, 2005)
    We present the long-term project on investigation of the absorption spectral features originating in interstellar HI clouds. This project is being realized at the Terskol Observatory. The most important results and the ...
  • Guseva, N.G. (Кинематика и физика небесных тел, 2005)
    We perform a comprehensive study of ten star-forming (SF) galaxies with the oxygen abundance Z<Z/20 [5] and blue extended low-surface-brightness components (LSB). Long-slit spectroscopy and V , I CCD photometry were obtained ...
  • Zhukovska, S.; Pavlenko, Ya.V. (Кинематика и физика небесных тел, 2005)
    Absorption CrH and FeH bands are of importance for study of atmospheres of ultracool dwarfs (Teff < 2200 K). Results from calculations of synthetic spectra of these objects using the new theoretical CrH and FeH opacities ...
  • Kulinich, Yu.; Novosyadlyj, B. (Кинематика и физика небесных тел, 2005)
    The evolution of matter density perturbations in the two-component model of the Universe filled with dark energy (DE) and dust-like matter (M) is considered. We have analysed it for two kinds of DE with ω ≠ −1: a) an ...
  • Gopka, V.F.; Yushchenko, A.V.; Shavrina, A.V.; Musaev, F.A. (Кинематика и физика небесных тел, 2005)
    We present a study of the chemical composition of atmospheres of five stars of the upper main sequence. Investigations of the SB2 system 66 Eri permit to find the gallium spots in atmospheres of the components, the secondary ...
  • Volvach, A.E.; Ryabov, M.I. (Кинематика и физика небесных тел, 2005)
    Observations of the millimeter wave emission variability of extragalactic radio sources may give an important information on active processes in their inner parts. The millimeter wave observations of extragalactic radio ...
  • Izotova, I.Y.; Parnovsky, S.L.; Izotov, Y.I. (Кинематика и физика небесных тел, 2005)
    A study of current star formation rates (SFRs) derived from Hα emission of ionized hydrogen for 1305 star-forming galaxies from the Sloan Digital Sky Survey (Data Release 1) is carried out. Current SFRs are derived from ...
  • Khalack, V. (Кинематика и физика небесных тел, 2005)
    The surface magnetic field structure of an ellipsoidal star is modelled in the frame of the magnetic charge description (MCD) approach. It is shown that the stellar oblation effect can lead to the essential overestimation ...
  • Shavrina, A.; Polosukhina, N.; Khan, S.; Pavlenko, Ya.; Khalack, V.; Wade, G.A.; Quine, t P.; Mikhailitska, N.; Yushchenko, A.; Gopka, V.; Kudryavtsev, D. (Кинематика и физика небесных тел, 2005)
    The lithium lines at 6708 Å for two sharp-lined roAp stars γ Equ and HD 166473 and at 6103 Å for γ Equ were analyzed in high resolution spectra. Three spectral synthesis codes – STARSP, ZEEMAN2, and SYNTHM – were used. New ...
  • Yakovina, L.A.; Pavlenko, Ya.V. (Кинематика и физика небесных тел, 2005)
    The resonance λ 670.8 nm and subordinate λλ 812.6, 610.4, 497.2, and 460.3 nm lithium lines are investigated as the lithium abundance indicators in spectra of cool C-giants.
  • Fedorova, E.V.; Alexandrov, A.N.; Zhdanov, V.I. (Кинематика и физика небесных тел, 2005)
    A study of gravitational microlensing of distant objects is presented. We performed simulations of light curves and trajectories of the image centroid of an extended source in the Chang–Refsdal lens with shear and continual ...
  • Bejar, V.J.S. (Кинематика и физика небесных тел, 2005)
  • Kaminsky, B.; Pavlenko, Ya.V. (Кинематика и физика небесных тел, 2005)
    We present the determination of the effective temperature, iron abundance, and microturbulent velocities for the pseudophotosphere of V838 Mon observed on February 25, March 2 and 26, 2002. Physical parameters of the line ...
  • Berczik, P.; Petrov, M.I. (Кинематика и физика небесных тел, 2005)
    In this paper we study the process of the subsequent (runaway) fragmentation of a rotating isothermal Giant Molecular Cloud (GMC) complex. Our own Smoothed Particle Hydrodynamics (SPH) gas-dynamical model successfully ...
  • Romanyuk, Ya. (Кинематика и физика небесных тел, 2005)
    We analyse the efficiency of observational campaigns which were carried out during seven years involving four astropoints in Ukraine, Russia, Greece, and Bulgaria. A possibility of the synchronous monitoring of stellar ...
  • Lyubchik, Yu.; Pavlenko, Ya.V.; Jones, H.R.A.; Tennyson, J.; Pinfield, D. (Кинематика и физика небесных тел, 2005)
    We present results of modelling the bulk of the spectral energy distribution (0.45–5 μm) for GJ406 (M6V). Synthetic spectra were calculated using the NextGen model atmospheres of Hauschildt et al. [6] and the incorporate ...
  • Pronik, I.I. (Кинематика и физика небесных тел, 2005)
    The first director of the Crimean Astrophysical Observatory academician G. A. Shajn actively studied the interstellar medium in the Galaxy and galaxies in the 1950s. He and his followers showed first that the interstellar ...
  • Novosyadlyj, B.; Apunevych, S. (Кинематика и физика небесных тел, 2005)
    Within the framework of cosmological inflationary models, relic gravitational waves arise as a natural consequence of the quantum nature of primordial space-time metric fluctuations and a validity of the general theory of ...
  • Fidelis, V.V. (Кинематика и физика небесных тел, 2005)
    The extra-galactic source blazar 3C 66A was observed in 2002 with the aid of the air Cherenkov telescope GT-48 dedicated for stereoscopic measurements of extensive air showers (EAS). The analysis of the observational data ...
  • Pavlenko, Ya.V. (Кинематика и физика небесных тел, 2005)
    We present results of modelling of spectra of M-, L-, T-dwarfs. Theoretical spectra are fitted to observed spectra to study the main parameters of the low-mass objects beyond the bottom of the Main Sequence. Application ...
