  • Das, Tanya; Banyal, R. K (Optical Society of America, 2021-11-01)
    Technological advancement has led to improvement in the design capabilities of astronomical spectrographs, allowing for high-precision spectroscopy, thereby expanding the realms of observational astronomy. High-resolution ...
  • Maheswar, G; Lee, C. W; Bhatt, H. C; Mallik, S. G. V; Dib, S (EDP Sciences, 2010-01)
    We aim to develop a method to determine distances to molecular clouds using JHK near-infrared photometry. Methods: The method is based on a technique that aids spectral classification of stars lying towards the fields ...
  • Ramesh, R; Kathiravan, C; Satya Narayanan, A; Ebenezer, E (The European Southern Observatory, 2003-03)
    We present metric radio observations of quasi-periodic emission from the solar corona in close association with a ``halo'' CME and an ``EIT wave'' phenomenon. The radio event lasted for about 60 s. Its mean periodicity was ...
  • Kathiravan, C; Ramesh, R; Subramanian, K. R (University of Chicago Press, 2002-03)
    We report metric radio observations and the results obtained using two-dimensional ray-tracing analysis of the solar corona close to the onset phase of the exceptionally bright prominence eruption and the associated massive ...
  • Ramesh, R; Kathiravan, C; Sastry, Ch. V (The American Astronomical Society, 2003-07-10)
    We report direct imaging observations of the propagation of a diffuse thermal radio enhancement in close temporal and spatial association with a ``halo'' coronal mass ejection from the solar atmosphere, in the metric ...
  • Kalita, Surajit; Sarmah, Lupamudra; Wojnar, Aneta (2023-02-15)
    We analyze the effects of modified gravity on specific heats of electrons and ions, Debye temperature, crystallization process, and cooling mechanism in white dwarfs. We derive the Lane-Emden-Chandrasekhar equation and ...
  • Parthasarathy, M; Parsons, S. B (1984-12)
    The Population II Cepheid pulsational variables AL Vir (P = 10.3 days) and W Vir (P = 17.3 days) were observed with IUE at two phases each. Only low-dispersion mid-UV exposures were feasible, but were sufficient to show a ...
  • Pant, V; Srivastava, A. K; Banerjee, D; Goossens, M; Chen, P.-F; Joshi, N. C; Zhou, Y.-H (IOP Publishing, 2015-10)
    We report and analyze observational evidence of global kink oscillations in a solar filament as observed in Hα by instruments administered by National Solar Observatory (NSO)/Global Oscillation Network Group (GONG). An ...
  • Satya Narayanan, A; Pandey, V; Venkatakrishnan, P (European Solar Physics, 2008-09)
    Propagation of magnetohydrodynamic (MHD) waves in inhomo- geneous magnetic plasmas is interesting from space and astrophysical point of view. In this study, the combined effect of non-parallel propagation, steady flow and ...
  • Banerjee, D; Krishna Prasad, S (John Wiley & Sons, Inc., 2015-05)
    Coronal holes are the dark patches in the solar corona associated with relatively cool, less dense plasma and unipolar fields. The fast component of the solar wind emanates from these regions. Several observations ...
  • Hasan, S. S (Indian Association for the Cultivation of Science, 1992)
    Theoretical aspects of wave propagation in an atmosphere with a vertical magnetic field are reviewed. Starting from the ideal magneto hydrodynamic equations. The differential equations governing linear oscillations presented ...
  • Gokhale, M. H (Astronomical Society of India, 1996)
    Our recent studies of rotation and magnetic field near the Sun's surface have indicated that the solar activity may be originating in interference of global torsional MHD oscillations in the Sun. Using theory of dynamics ...

  • Vagiswari, A; Kameswara Rao, N; Birdie, C; Priya Thakur (Indian Institute of Astrophysics, 2009-03)
  • Saha, S. K; Yeswanth, L (Anita Publications, 2004)
    The atmospheric coherence is a highly variable parameter depending upon the high velocity wind. The size of the atmospheric coherence length widely known as, Fried's parameter, ro, has been computed during night at the ...
  • Krishan, V; Ramadurai, S; Wiita, P. J (The European Southern Observatory, 2003-02)
    We have investigated the phenomenon of explosive chromospheric evaporation from an accretion disk as a mechanism for fast variability in accreting sources such as low mass X-ray binaries and active galactic nuclei. This ...
