    We report the CaII K observations of a major umbral solar flare of optical class 3B which occurred on 1989 March 13. Correlated optical, microwave, soft X-ray (SXR), sudden ionospheric disturbance observations and the ...
  • New approach for inclusion of the effect of gravity in magnetohydrostatic equilibrium in solar coronal arcades 
    Prasad, L; Chandra, S (Astronomical Society of India, 1992)
    The study presents a novel approach for the inclusion of the effect of gravity in the magnetohydrostatic equilibrium in coronal arcades, in which the magnetic lines of force are unaffected whereas the pressure isobars are ...
  • Can HeH(+) molecule be present in solar photosphere 
    Gaur, V. P; Joshi, G. C; Pande, M. C (Astronomical Society of India, 1992)
    The equivalent widths of the P and R branch lines of the fundamental vibration-rotation band arising from the ground state of HeH(+) have been calculated in a chosen photospheric model. The resulting equivalent widths ...
  • The most distant radio galaxies 
    Kapahi, V. K (Astronomical Society of India, 1992)
    The techniques and samples being employed to find radio galaxies at high redshifts are outlined. Results obtained from the study of high-redshift galaxies, as well as attempts to elucidate this phenomenon are discussed. ...

    Gupta, K. G; Pande, M. C (Astronomical Society of India, 1992)
    The status of various applications of speckle interferometry and imaging to the study of solar granulations as well as solar activity is reviewed. The physical aspects of solar granulations are examined, with emphasis on ...
  • Chemical evolution of the solar neighbourhood 
    Rana, N. C (Astronomical Society of India, 1992)
    The study presents a simple model of the chemical evolution of the solar neighborhood with reference to the evolution and frequency distribution of a particular element - iron. The history of star formation in the solar ...
  • Cosmology - Particle physics interface

    Some of the areas of cosmology which have been activated by new developments in particle physics are reviewed. A brief review of the essential ideas of the big bang model and models of particle physics with spontaneously ...
  • Strengths and weaknesses of the big bang cosmology 
    Narlikar, J. V (Astronomical Society of India, 1992)
    The achievements and shortcomings of the standard hot big bang models of the universe are reviewed. The achievements lie in the predictions of the expanding universe, the abundances of light nuclei, and the MW background. ...
  • Galaxy formation 
    Padmanabhan, T; Subramanian, K (Astronomical Society of India, 1992)
    An attempt is made to develop a consistent theory describing galaxy formation. First, a discussion of the smooth universe is presented. The linear theory of perturbations is introduced, and its applications are described. ...
  • The growth of publications of the Astronomical Society of India 
    Gupta, S. K; Sinha, K (Astronomical Society of India, 1991)
  • Expedition to Mauritius for observing supernova 1987A 
    Babu, G. S. D; Bhatnagar, A. K; Narayanan, R. S (Astronomical Society of India, 1991)
    A two-member expedition to the island country of Mauritius was organized in February/March 1988 to observe the supernova 1987A photometrically. The only occasion when one complete set of observations of SN 1987A could be ...
  • The Kodaikanal solar vector magnetograph - Laboratory evaluation of the polarimeter 
    Venkatakrishnan, P; Narayanan, R. S (Astronomical Society of India, 1991)
    Laboratory experiments performance to evaluate the sensitivity of the polarimeter of the Kodaikanal vector magnetograph. The polarimeter does not produce significant cross talk and has a sensitivity of about 1 percent polarization
