  • High resolution spectroscopy of the R Coronae Borealis star, V854 Centauri, during a deep minimum 
    Kameswara Rao, N; Lambert, D. L (American Astronomical Society, 1993-05)
    The R Coronae Borealis star V854 Cen was observed at minimum light (V about 15) at high spectral resolution from 5480 to 7070 A. The spectrum consists of three components: a continuum devoid of photospheric lines, a ...
  • 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 ...
  • Reddening and dust distribution around V348 SGR 
    Kameswara Rao, N; Nandy, K (Bruxelles : Palais des Académies, 1988)
    Radio and Brackett gamma observations indicate large value of reddening E(B - V) = 1.5 to the nebula surrounding V348 Sgr, where as the star appears to be reddened by only E(B - V) is approximately 0.4. The infrared ...
  • Spectroscopic studies of R CrB during light minima - Absorption spectrum 
    Kameswara Rao, N; Giridhar, S; Ashoka, B. N (Royal Astronomical Society, 1990-05)
    R CrB was observed during the 1986 shallow minimum to study the spectral changes taking place during light minimum as compared with the spectrum at maximum light. The absorption spectrum at this minimum is very similar to ...
