  • Fast Photometry Uisng CCD 
    Srinivasan, R; Muralishankar, S; Rajamohan, R (Indian Institute of Astrophysics, Bangalore, 1991)
    Observations of certain objects which exhibit fast changes in their light output seems to be of great interest in optical astronomy. Important informations can be obtained on their internal structures of the stars through ...
  • Infrared Photometer system for Astronomical Observations 
    Shivanandan, K; Scaria, K. K; Nair, R. M; Rajamohan, R; Sivaraman, K. R (Indian Institute of Astrophysics, Bangalore, 1987)
    An infrared photometer system has been developed for photometry of astronomical sources in the spectral band 1 to 5 microns. The characteristics of the system and preliminary engineering tests using the 1- m optical ...
  • NU Centauri: A New Beta Cephei Star 
    Rajamohan, R (Indian Institute of Astrophysics, Bangalore, 1977)
    Spectroscopic observations of the single-lined binary, NU Centauri during the years 1968-1972 were utilised to derive fresh orbital elements of this system. The measured radial velocities indicate that the primary component ...
  • Observations of the Corona at the Eclipse of 1983 June 11. I. Temperature and Rotation of the Corona from 5303A and 6374A profiles 
    Singh, J; Sivaraman, K. R; Rajamohan, R (Indian Institute of Astrophysics, Bangalore, 1988)
    During the total solar eclipse of 1983 June 11, coronal spectra were obtained in the 5303A (Fe XIV) line using the multislit spectrograph at a dispersion of 2.17A mm-1 . The line profiles measured at 113 locations from ...
