  • Ca II K Emission in Canopus 
    Bappu, M. K. V; Mekkaden, M. V; Kameswara Rao, N (Astronomical Society of India, 1984-06)
    The Changes in the Ca II K line profile of the F0 supergiant Canopus have been studied from the high dispersion coude spectrograms obtained since 1975. The emission in the core of the line is variable in a timescale of few ...
  • Evolution of Optical Spectrum of SN 1987A 
    Kameswara Rao, N (Indian Institute of Astrophysics, 1988)
    The initial reaction to the spectroscopic behaviour of SN 1987A was that it is a very untypical SN II but after a year, it is said that it is not peculiar after all. Only it went through various stages very fast and that ...
  • The great september comet of 1882 II (C\1882 R1) that transited over the Sun - Pogson's observations from Madras Observatory 
    Kameswara Rao, N; Vagiswari, A; Birdie, C (Indian Institute of Astrophysics, 2007-06)
  • Madras Observatory 
    Vagiswari, A; Birdie, C; Kameswara Rao, N (IIA Archives, 2006)

  • 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 ...
