  • 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 ...
  • Supernova SN 1987A - Rotation rate of the central pulsar 
    Bhatt, H. C; Datta, B (Royal Astronomical Society, 1989-04)
    Using available observational data on supernova SN 1987A, firm quantitative lower limits on the rotation period of the central pulsar (assuming the pulsar luminosity to power the supernova light curve) are derived. It is ...
  • UBV Observations of R-Coronae Type Variables and Related Objects 
    Kameswara Rao, N (D. Reidel Publishing Co., 1980-07)
    UBV observations obtained during the period 1972-73 are presented for the following five R CrB stars: GU Sgr, SU Tau, XX CAm, DZ And, V973 Oph, and the hydrogen-poor, carbon-rich stars BD + 10 deg 2179 and HD 137613. ...
  • 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.
