  • 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 ...

    A brief description of the sky survey project taken up with the 45 cm Schmidt telescope of the Vainu Bappu Observatory at Kavalur is given. Positions of 11 asteroids detected on plates taken during 1987 Feburary-March are reported
  • Project Kalki - A sky survey with the Schmidt telescope. 2 
    Rajamohan, R; Shankar, P. N; Bhattacharyya, J. C; Kuppuswamy, K; Paranjpye, A (Astronomical Society of Indian, 1988-03)
    The region of the sky photographed with the 45cm Schmidt telescope during 1987 March-May and the position of the asteroids detected on these plates are reported in this paper. Out of the 29 asteroids observed four have ...
  • Some further measurements of Uranian ring condensations 
    Vasundhara, R; Bhattacharyya, J. C; Rajamohan, R; Mahra, H. S (Kluwer Academic Publishers, 1983)
    The results of photometric observations of the occultation of BD-19 degree 4222 by Uranus on April 26, 1981 from two stations in India conform with the model proposed by Elliot et al. (1981).
  • Variable stars in the old galactic cluster M67 
    Rajamohan, R; Bhattacharyya, J. C; Subramanian, V; Kuppuswamy, K (Astronomical Society of Indian, 1988-12)
    Schmidt plates of the old open galactic cluster M67 were obtained on twelve nights to find the most probable variables in the cluster. The Sabattier technique was used to derive the magnitudes of the cluster members. The ...
