  • Presence of Mg II emission in R Coronae Borealis at maximum light 
    Kameswara Rao, N; Nandy, K; Bappu, M. K. V (Royal Astronomical Society, 1981-06)
    The high dipersion spectrum of R CrB in the long wavelength obtained near its maximum with the International Ultraviolet Explorer shows the presence of chromospheric Mg II emission. For comparison the spectrum of Gamma Cyg ...
  • 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 ...
  • Search for CO (1-0) emission in R CrB with large infrared excesses 
    Kameswara Rao, N; Nyman, L. A; Nandy, K; Houziaux, L (Cambridge University Press, 1991)
  • Ultraviolet observations of the hydrogen-deficient variable star MV Sagittarii 
    Kameswara Rao, N; Nandy, K (Indian Academy of Sciences, 1982)
    IUE observations of the hydrogen-deficient irregular variable star MV Sgr obtained in June-October 1980 and November 1979 are discussed. The observations reveal a prominent 2200 A absorption feature. A value of E(B - V) = ...
  • 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. ...
