  • 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 ...
  • Future Trends in Stellar Spectroscopy

  • A Survey of Red Stars in the Direction of the Large Magellanic Cloud. III. Some Regions North of Bar 
    Bappu, M. K. V; Parthasarathy, M; Scaria, K. K (Indian Institute of Astrophysics, Bangalore, 1985-11)
    We have continued the survey for red stars in the direction of the Large Magellanic Cloud using the technique of ultra-low dispersion spectroscopy. In this paper we list 310 red stars located north of L M C bar. Finding ...
  • The Absolute Magnitudes of Wolf-Rayet Stars HD 151932 and HD 152270 
    Shylaja, B. S; Bappu, M. K. V (Indian Institute of Astrophysics, Bangalore, 1983)
    The absolute visual magnitudes of two Wolf-Rayet stars HD 151932 (WN 7) and HD 152270 (WC 7+08) have been determined from their energy distributions and monochromatic magnitudes least contaminated by emission lines taking ...
  • On the light curves of RX Librae and TV Canis Majoris 
    Bappu, M. K. V (1950)
  • The Wolf-Rayet Spectrscopic Binary HD 214419 
    Bappu, M. K. V; Visvanadham, P (Indian Institute of Astrophysics, Bangalore, 1977)
    Velocity curves of the system HD 214419 are obtained for the N IV 4058 and He II 4686 emission lines from prismatic spectra taken in 1951 and 1952. The emission and absorption features experience several phase dependent ...
  • A Survey of Red Stars in the Direction of the Large Magellanic Cloud: The 30 Doradus Region 
    Bappu, M. K. V; Parthasarathy, M; Scaria, K. K (Indian Institute of Astrophysics, Bangalore, 1977)
    We have commenced a survey of red stars in the direction of the Large Magellanic Cloud using the technique of ultra-low dispersion spectroscopy. This first paper is a listing of the red stars in the 30 Doradus region for ...
  • An Automated Spectrum Scanner 
    Bappu, M. K. V (Indian Institute of Astrophysics, Bangalore, 1977)
    A rapid-scan single channel spectrum in the Ebert-Fastie arrangement has been constructed and successfully used on the Kavalur 102-cm reflector. The special region 3000-11000 Armstrong is covered with appropriate dry-ice ...
  • The Near Infrared Spectra of Wolf Rayet Stars 
    Bappu, M. K. V; Ganesh, K. S; Scaria, K. K (Indian Institute of Astrophysics, Bangalore, 1977)
    The near infrared spectra of three Wolf-Rayet stars of the carbon sequence and five of the nitrogen sequence have been studied. Wavelength identifications and intensity scans are presented to show the emission line ...
  • Ultra-low dispersion spectroscopy of stars and galaxies 
    Bappu, M. K. V; Parthasarathy, M (Indian Institute of Astrophysics, Bangalore, 1977)
    Application of ultra-low dispersion spectroscopy (10.000 Å mm-1) is described to study the nuclei of elliptical galaxies, the quassi - stellar objects and for the discovery of faint OB stars, reddened stars and red stars. ...
  • The Solar Corona of July 20, 1963 
    Bappu, M. K. V; Bhatnagar, A (Kodaikanal Observatory, 1969-01)
    The total solar eclipse of July 20, 1963 was observed at the AAVSO site near Wilton, Malne, U.S.A, where totality lasted for 58 seconds. Pictures of the corona were obtained with a camera of focal length 57 cm on Kodak ...
  • Comet Ikeya-Seki (1965) and the nature of the Interplanetary Medium During its Apparition 
    Bappu, M. K. V; Sivaraman, K. R (Kodaikanal Observatory, 1969-01)
    The effects of a solar wind on the different parts of a comet are discussed. In terms of the observations obtained of Comet Ikeya-Seki (1965f). The solar wind contribution to the formulation of the scattering agencies in ...
  • The Spectrum of Comet Ikeya-Seki (1965f) 
    Bappu, M. K. V; Sivaraman, K. R (Kodaikanal Obsevatory, 1966-12)
    Spectroscopic observations of Comet Ikeya-Seki (1965f) with slit and slitless instruments are described. Sodium emission in the coma is seen from October 9 to November 1. A sodium tail extending upto 2 degree from the ...
