  • Spectral evolution of nova V443 Scuti 1989 
    Anupama, G. C; Duerbeck, H. W; Prabhu, T. P; Jain, S. K (European Southern Observatory, 1992-09)
    Spectroscopy of the moderately fast nova V443 is presented. Observations were made during the brightness fluctuations following maximum and during the transition stage. A few broadband polarimetric observations are also ...
  • Spectrophotometric studies of CO Cephei 
    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 ...
  • Spectrophotometry of Nova Coronae Austrinae, 1981 
    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 ...
  • Spectroscopic observations of Nu Centauri 
    Ashoka, B. N; Surendiranath, R; Kameswara Rao, N (Copernicus Foundation for Polish Astronomy, 1985)
    Presented are radial-velocity observations of the single-line spectroscopic binary and Beta Cephei-type variable Nu Cen, obtained in the period 1983-1984. New orbital elements have been determined by combining these ...
  • Study of the Wolf-Rayet members of the cluster NGC 6231 
    Shylaja, B. S (Indian Academy Sciences, 1988-09)
    Two Wolf-Rayet members of the cluster NGC 6231 are studied spectrophotometrically. HD 151932, a suspected variable, shows variations in the emission line flux as well as continuum magnitude measurements. An attempt is made ...
  • The variability of HD 76536 
    Shylaja, B. S (Kluwer Academic Publishers, 1990-02)
    The spectrophotometric and photometric observations of the WC star HD 76536 are reported. The flux and the magnitude variations appear to be periodic. The possibilities of a compact binary are discussed.
