  • A D. C. Amplifier for Photoelectric Photometry 
    Raveendran, A. V; Mohin, S (Indian Institute of Astrophysics, Bangalore, 1987)
    We describe the construction and discuss the performance of a d.c. amplifier which was installed at the 34-cm telescope of Vainu Bappu Observatory in 1987 January and since then extensively used for variable star photometry.
  • Photometry of Zeta Aurigae during the 1977 and 1979-80 Eclipses 
    Mohin, S; Raveendran, A. V; Mekkaden, M. V (Indian Institute of Astrophysics, Bangalore, 1980)
    UBV photometry of Zeta Aurigae during the 1977 and 1979-80 eclipses is presented. From an analysis of the available photometry, it is concluded that the long term intrinsic variation in the brightness of the late-type super ...
