  • Joshi, S. C; Ojha, D. K (Astronomical Society of India, 1991)
    Two high rotational velocity B type stars HR 1207 and HR 1770 have been observed spectrophotometrically. The energy distribution curves of the stars have been compared with model atmospheres in the ultraviolet and visible ...
  • Rautela, B. S; Joshi, G. C; Srivastava, J. B (Astronomical Society of India, 2000)
    Haser Model production rates of CN and C2 in the coma of the comet Hale-Bopp (C/1995 O1) have been obtained. Molecular production rate, size of the nucleus and continuum flux at 484.0 nm have further been analysed to get ...

  • Kameswara Rao, N; Vasundhara, R; Ashoka, B. N (D. Reidel Publishing Co, 1986)
  • Singh, M; Sanwal, B (Astronomical Society of India, 1996)
    Using EG & G spectrograph coupled with reticon array detector and Optical Multichannel Analyser (OMA) at the Cassegrain focus of the 104 cm telescope of the U.P. State Observatory, Naini Tal, several well known bright Be ...
  • Sanwal, B. B; Rautela, B. S; Mahendra Singh; Srivastava, J. B (Astronomical Society of India, 1993)
    Periodic comet Swift-Tuttle (1992t) period 135 years was observed with 104 cm reflector of Uttar Pradesh State Observatory, Naini Tal, using OMA (Optical Multichannel Analyser) reticon array detector in the visible region ...
  • Babu, G. S. D; Shylaja, B. S (D. Reidel Publishing Company, 1982-04)
    The relationships among the various physical parameters, namely the effective temperatures, radii and bolometric magnitudes, determined on the basis of the energy distribution curves of 25 Am stars are investigated. The ...
  • Babu, G. S. D; Shylaja, B. S (D. Reidel Publishing Company, 1982-01)
    Based on the observed energy distribution curves of about a hundred Ap stars, the various relationships among their physical parameters: namely, the temperatue, colour index, bolometric correction and bolometric magnitude ...
  • Shylaja, B. S (Indian Academy of Sciences, 1986-09)
    Spectrophotometric and spectroscopic observations of CQ Cep, the shortest-period binary with a WN component, are presented. Excepting the N V 4603 A, the fluxes of all other emission lines show enhancement at minima. They ...

  • Singh, M; Sanwal, B. B (Astronomical Society of India, 1998)
  • Shylaja, B. S (Indian Academy of Sciences, 1986-12)
    New spectrophotometric observations of the Wolf-Rayet system HD 50896 are presented and interpreted in terms of its binary nature. The lines of N V, N IV and C IV show moderate variations which can be explained using a ...
  • Babu, G. S. D (Astronomical Society of India, 1998)
  • Sivaraman, K. R; Babu, G. S. D; Shylaja, B. S; Rajamohan, R (European Southern Observatory, 1987-11)
    The authors made spectral scans of comet P/Halley using the scanner at the Cassegrain focus (f/13) of the 102 cm reflector at Kavalur. The scans cover generally the wavelength region from 3900 to 6200 Å and are at 40 Å ...
  • Shylaja, B. S (D. Reidel Publishing Co., 1984-10)
    Spectrophotometric observations of Nova Coronae Austrinae 1981, during its nebular phase are reported. The various emission lines are identified. The electron densities and the mass of the ionized hydrogen in the shell ...
  • Shylaja, B. S (The observatory, 1983-08)
  • Shylaja, B. S (European Space Agency, 1985)
    The Spectrophotometric observations of the nova Vulpeculae, 1984, # 1 obtained at the Kavalur observatory in September 1984 have been identified and compared with other novae. The nova appears to be in the early decline ...
