  • The wandering pole 
    Hart, Henry (Astronomical Society of India, 1913-03)
  • Warp of the Galactic Disk as seen in Mid Infrared from Midcourse Space Experiment 
    Vig, S; Ghosh, S. K; Ojha, D. K (Astronomical Society of India, 2003)
    The nature of the warp structure in the distribution of stellar as well as warm interstellar dust (WISD) components in the Galactic disk has been investigated using respective mid infrared emissions. Such a study with high ...
  • Wave leakage in a magnetized isothermal atmosphere 
    Banerjee, D; Hasan, S. S; Christensen-Dalsgaard, J (Astronomical Society of India, 1996)
    The present investigation is a continuation of earlier work by Hasan & christensen-Dalsgaard (1992) and Banerjee, Hasan & Christensen-Dalsgaard(1995), where the interaction of various elementary modes in a stratified ...
  • Wave propagation in solar magnetic tubes 
    Venkatakrishnan, P (Astronomical Society of India, 1981-09)
    The work done on propagation of waves in magnetic tubes is reviewed. It is seen that majority of the results obtained so far are based on the thin tube approximation. It is shown that estimates of the mechanical energy ...
  • Wavefront sampling technique : VHE gamma-ray experiments in India 
    Bhat, P. N (Astronomical Society of India, 2002)
    Atmospheric Cverenkov techniques is the only method which has been successfully used to probe the sky in the TeV energy band. However it has certain intrinsic drawbacks arising primarily out of the presence of cosmic rays ...
  • Weak cyanogen lines in the solar spectrum in the 4139 A-4215 A region 
    Porfir`eva, G. A (Astronomical Society of Indian, 1986-03)
    The identification reliability of solar spectrum cyanogen lines in the 4139-4215 A region is considered in connection with the study of velocity fields by means of line profile analysis. The identification of most of the ...
  • What can be the real nature of gravitational force 
    Ridsdale, A. C (Astronomical Society of India, 1916)
  • What do we know about neutron stars? 
    Kundt, W (Astronomical Society of India, 1985-03)
  • What is a quiet sun CaII K line profile? 
    Sivaraman, K. R; Gupta, S. S; Kariyappa, R (Astronomical Society of India, 1993)
    We have derived a mean disc averaged K line profile from observations at the Kodaikanal Solar Tower Telescope on days when sun was relatively very quiet during the years 1985-86. This mean profile would represent the K-line ...
  • What is the physical condition of sun's interior 
    Ridsdale, A. C (Astronomical Society of India, 1916)
  • What's New With Hale Bopp? 
    Shylaja, B. S (Astronomical Society of India, 1997)
  • White dwarfs in the 1990's 
    Trimble, V (Astronomical Society of India, 1999)
    White dwarfs are the last evolutionary phase in the lives of stars that begin with up to about eight times the mass of our sun (8M). Their unique property is that the force of gravity is balance not by ordinary gas pressure ...
  • White Light and Emission Line Polarization of Solar Corona during TSE of June 21, 2001 
    Ambastha, A; Gosain, S (Astronomical Society of India, 2003)
    Coronal intensity and polarization maps have been obtained for the total solar eclipse (TSE) o o of June 21, 2001, observed from Lusaka, Zambia (location: 28 17.5E 15 24.5S, Alt. 1300 mtr) at broadband H 6563Å (FWHM 80Å), ...
  • Whither strange pulsars? 
    Konar, S (Astronomical Society of India, 2000)
    It has been argued that some of the pulsars could be strange stars because these too are capable of supporting fast rotations observed in pulsars. We examine this claim from the point of view of the evolution of magnetic ...
  • Why not Give Mars a Ring like that of Saturn? 
    Chiplonkar, M. W (Astronomical Society of India, 1978-09)
    With a view to test the famous Roche hypothesis, it is suggested that, in the near future space programme, Phobos, the inner satellite of Mars, be pushed inside by a properly arranged atomic explosion so as to cross the ...
  • Why quantum mechanics is complex 
    Wheeler, J. T (Astronomical Society of India, 1997)
    The zero-signature Killing metric of a new, real-valued, 8-dimensional gauging of the conformal group accounts for the complex character of quantum mechanics. The new gauge theory gives manifolds which generalize curved, ...
  • Wide Field CCD Photometry of the Young Open Cluster NGC 663 
    Pandey, A. K; Upadhyay, K; Ogura, K; Sagar, R (Astronomical Society of India, 2003)
    A deep and wide field CCD photometry of the young open cluster NGC 663 has been carried out. We report preliminary results of our investigations, specifically the determination of the cluster mass function which is found ...
  • Wind induced instabilities in accretion flow around black holes 
    Acharya, K; Chakrabarti, S. K; Molteni, D (Astronomical Society of India, 2002)
    We identify a new type of instability of the accrelation flow which is formed due to interaction of the outgoing winds with the incoming flow. Mainly due to shear instability, the flow oscillates around the equatorial ...
  • Window-threshold technique for detecting pulse components 
    Gangadhara, R. T (Astronomical Society of India, 2000)
    We have analysed high-quality single pulse data of PSR B0329+54 at 606 MHz to study the structure of the emission beam. In order to unambiguously detect weak emission components in the integrated pulse profile, we have ...
  • Winter School on High Energy Astrophysics 
    Narlikar, J. V; Chitre, S. M (Astronomical Society of India, 1976-06)
