  • 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)
  • Wolf-Rayet galaxies and their CCD photometry 
    Sanwal, B. B (Astronomical Society of India, 2001)
    Galaxies with Wolf-Rayet star features in their spectra have long been known. They are characterised by a broad emission feature at ? 4686 Å. This is attributed to stellar HeII emission from a large population of WR stars. ...
  • Workshop on Plasma Physics 
    Buti, B (Astronomical Society of India, 1977-03)
  • A Wrap in the LMC Bar? 
    Subramaniam, A (Astronomical Society of India, 2003)
  • X-Ray Astronomy in 1974 
    Peterson, L. E (Astronomical Society of India, 1974-09)
  • X-ray burster and nuclear reaction rates 
    Rani Deka, I; Duorah, K; Duorah, H. L (Astronomical Society of India, 1996)
  • X-ray bursts from GRS 1915+105 observed with IXAE 
    Yadav, J. S; Agrawal, P. C; Paul, B; Rao, A. R; Vahia, M. N; Seetha, S; Kasturirangan, K (Astronomical Society of India, 1999)
    The light curves of the galactic superluminal X-ray transient source GRS1915+105 observed with the pointed proportional counters (PPC) of Indian X-ray Astronomy Experiment (IXAE)on board IRS-P3 have revealed the presence ...
  • X-ray Emissions from the Jovian System 
    Bhardwaj, A (Astronomical Society of India, 2003)
    X-ray emissions from Jupiter, discovered by Einstein observatory and followed up by ROSAT, have been thought to be excited by energetic and highly charged sulphur and oxygen ions precipitating from the inner magnetosphere ...
  • The X-ray observation of newly discovered transient XTE J1748-288 by the Indian X-ray Astronomy Experiment 
    Naik, S; Agrawal, P. C; Paul, B; Rao, A. R; Seetha, S; Kasturirangan, K (Astronomical Society of India, 2000)
    The observations of X-ray transient XTE J1748-288 were made in the energy band 2 - 18 keV with the Indian X-ray astronomy experiment (IXAE) during 1998, June 14-25 with total useful exposure of 27,100 second for 1 sec ...
  • X-ray orbital modulations in low-mass X-ray binaries 
    Pandey, U. S (Astronomical Society of India, 1990)
    It is suggested that structure in the outer parts of the accretion disk of low-mass X-ray binaries may be due to tidal action of the secondary which is overflowing its Roche lobe. These structures at various phases may ...
  • X-ray Spectroscopy of the HMXB Pulsar GX 301-2 with Chandra 
    Mukherjee, U; Paul, B (Astronomical Society of India, 2003)
    We present analysis of X-ray spectra of the accreting pulsar GX 301-2, from two observations with the Chandra X-ray observatory made during different phases of its orbital period. Analysis of the zeroth order ACIS spectra ...
  • X-ray structure of clusters of galaxies with ROSAT 
    Singh, K. P (Astronomical Society of India, 1993)
    X-ray emission from clusters of galaxies is due to thermal Bremsstrahlung from a hot thin gas in the intergalactic medium. The gas is generally considered to be smoothly distributed with a size of approximately 3 Mpc. X-ray ...
  • X-ray studies of Be/X-ray binaries 
    Saraswat, P (Astronomical Society of India, 1993)
