  • Observations of Optical Emission from X-Per and SCO X-1 
    Sharma, P. D; Nagaraja, V. B; Marar, K. T. M; Bhattacharyya, J. C; Mohin, S (IUPAP, 1981)
    High speed photometric observations of X-per, and SCO X-1 have been carried out during 1979-80 with the 102cm and 33cm telescope at the Kavalur observatory. Results from some of these observations are presented in this ...
  • Observations of X-Per in optical domain 
    Sharma, D. P; Nagaraja, B. V; Bhattacharyya, J. C; Mohin, S; Raveendran, A. V (Kluwer Academic Publishers, 1983-09)
    We have monitored the X-ray source X-Per (4U 0352+30) on 31 August, 1979 through aU filter for about 1.5 hr using 102-cm telescope of Kavalur observatory. During this period intensity of X-Per fluctuated for some time, on ...
  • Observing conditions for optical astronomy at Leh 
    Singh, J; Bhattacharyya, J. C; Babu, G. S. D; Ashoka, B. N; Appakutty, M; Rangarajan, K. E; Kutty, K. N; Moorthy, V; Selvakumar, G; Michael, P; Muniyandi, A; Gabriel, F (Astronomical Society of India, 1989-09)
    The sky and atmospheric conditions at Leh have been monitored since 1984 with a view to determining its suitability as a site for a high-altitude observatory. During May-November, 1987, relative humidity and other parameters ...
  • Occultation: A precise method in astronomical studies 
    Bhattacharyya, J. C (Indian Academy of Sciences, 1982-05-09)
  • On emission lines of hydrogen, helium and ionized calcium seen on a coronal spectrogram of the march 7, 1970 eclipse 
    Bappu, M. K. V; Bhattacharyya, J. C; Sivaraman, K. R (D. Reidel Publishing, 1972-10)
    Emission lines of the Balmer series, D3 and H and K are reported present on a coronal spectrogram obtained at the March 7, 1970 eclipse. Arguments are presented to show that these could not have originated from scattering ...
