  • The hot R Coronae Borealis star DY Centauri: Nebular and photospheric lines 
    Kameswara Rao, N; Giridhar, S; Lambert, D. L (The European Southern Observatory, 1993-12)
    High resolution spectra in the red region of the hot R CrB star DY Cen show the following characteristics: a strong absorption line spectrum dominated by lines of C II, N II, and Ne I inverse P-Cygni type profiles of some ...
  • The infrared fluxes of early type stars 
    Shylaja, B. S (Astronomical Society of India, 1994)
    It is well known that the strong winds of the early type stars modify the fluxes in the infrared and radio wavelength regions. This aspect has been used here to explain the infrared fluxes by the method of 'curve of growth'. ...
  • Some experiments in radiative transfer 
    Abhyankar, K. D (Astronomical Society of India, 1999)
  • A spectrophotometric study of the Wolf-Rayet star HD 50896 
    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 ...
  • A study of the Cometary Globules in the GUM Nebula 
    Sridharan, T. K (Astronomical Society of India, 1993)
    Among the smaller interstellar molecular clouds the Cometary Globules (CGs) stand out due to their peculiar morphology. They are characterized by compact, dusty heads with long faintly luminous tails extending on one side ...
  • The ultraviolet spectrum of the hydrogen-poor binary HD 30353 
    Parthasarathy, M; Hack, M; Tektunali, G (The European Southern Observatory, 1990-04)
    An analysis is made of the high- and low-resolution UV spectra of the hydrogen-poor star HD 30353. The stellar wind profiles of the resonance lines of N V, C V, and Si IV are found to be similar to those observed in Upsilon ...
  • The UV spectrum of the WC 11 star CPD -56 deg 8032 
    Kameswara Rao, N; Giridhar, S; Nandy, K (The European Southern Observatory, 1990-08)
    UV observations of the WC 11 central star of the compact planetary nebula CPD -56 deg 8032 show that the continuum flux is variable. This variability appears to be caused by a change in the circumstellar extinction properties. ...
