  • Astrometry of Comet Halley during the 1985-86 apparition 
    Bagare, S. P; Scaria, K. K (Astronomical Society of Indian, 1988)
    Photographs of Comet Halley were obtained using the 1-m telescope of the Vainu Bappu Observatory, Kavalur, during the 1985-86 apparition, and astrometric measurements carried out. The details of the observations and the ...
  • Magnetic field and the ionic tail of comet Halley 
    Krishan, V; Ramadurai, S (Astronomical Society of Indian, 1988-03)
    The space missions to comet Halley have reported an increase of the magnetic field from (12-15) x 10 to the -5th gauss, characteristic of the interplanetary solar wind, to a peak field strength of (70-80) x 10 to the -5th ...
  • Narrow band photometry of Comet Halley in the emission bands and the continuum 
    Babu, G. S. D; Nathan, J. S; Rajamohan, R; Sivaraman, K. R (Astronomical Society of Indian, 1989-09)
    IHW filter photometry of Comet Halley was carried out on seven nights during pre-perihelion period and on six nights during post-perihelion period, using the 40-cm telescope at the Vainu Bappu Observatory, Kavalur, as a ...
  • Optical depth towards the nucleus of Halley's comet 
    Shah, G. A (Astronomical Society of Indian, 1989-09)
    A new relation between the nuclear radius and the optical depth toward the nucleus of Comet Halley has been derived on the basis of the radial variation of the effective area of the grains along the Giotto trajectory in ...
  • Photographic astrometry of Comet Halley 
    Ballabh, G. M; Kilambi, G. C; Sanwal, N. B; Sreedhar Rao, S; Swaminathan, R; Raghavender Rao, C (Astronomical Society of Indian, 1989-12)
    The 20-cm astrograph of the Nizamiah and Japal-Rangapur Observatoies in India was used to obtain photographic plates of Comet Halley before and after perihelion during the 1985-1986 apparition. The images are reduced and ...
