    Mohan, V; Pandey, A. K (Astronomical Society of India, 1984-09)
    Photoelectric magnitudes of 26 stars in the field of King 21 have been obtained. The reddening is variable across the cluster. A distance of 1.91 kpc has been estimated for the cluster. It is concluded that the age of the ...
  • Photometry of open cluster STOCK 17 
    Pandey, A. K (Astronomical Society of Indian, 1986-03)
    Photoelectric magnitudes of 10 stars in the field of Stock 17 have been obtained. The reddening is uniform across the cluster. A distance of 2.12 kpc has been estimated for the cluster. It is concluded that the age of the ...
  • Photometry of Solar Corona to Study the Coronal Structures 
    Chakraborty, P; Sankarasubramanian, K; Majumder, S; Rajesh Nayak, K; Sridharan, R; Jana, A. D; Rajalakshmi, G; Suresh, D; Asgekar, A; Geetha, K. P; Rajesh, C. K (Indian Institute of Astrophysics, Bangalore, 1997)
    White light images of the solar corona were taken on KODAK 2415 films using 3-inch (f/11.5) telescopes fitted with SLR cameras. Observations were made from 4 different sites spread over the totality belt by four different ...
  • Photometry of the Rs-Canum Binary II-PEG 
    Mohin, S; Raveendran, A. V; Mekkaden, M. V (International Astronomical Union, 1986)
    B and V photometry of II Peg obtained at Kavalur on 39 nights during 1980 - 81, 1981 - 82 and 1984 - 85 is presented. From an analysis of the available data on this object the authors find that no two light curves agree ...
