  • Wide Field CCD Photometry of the Young Open Cluster NGC 663 
    Pandey, A. K; Upadhyay, K; Ogura, K; Sagar, R (Astronomical Society of India, 2003)
    A deep and wide field CCD photometry of the young open cluster NGC 663 has been carried out. We report preliminary results of our investigations, specifically the determination of the cluster mass function which is found ...
  • Young LMC star clusters as a test for stellar evolutionary models. 
    Subramaniam, A; Sagar, R (The European Southern Observatory, 1995-05)
    We compare the observed colour-magnitude diagrams (CMD) and the main sequence luminosity functions (LFs) of four Large Magellanic Cloud (LMC) star clusters namely, NGC 1711, NGC 2004, NGC 2164 and NGC 2214 with the synthetic ...
  • The Young Open Star Clusters: Stability and Structure 
    Pandey, A. K; Mahra, H. S; Sagar, R (American Astronomical Society, 1990-02)
    It is found to the differential extinction ΔE (B-V) in open clusters which may be due to the presence of gas and dust, decreases systematically with age of the cluster. Consequently we can infer that the average gas removal ...
  • Young star clusters of our galaxy and the large magellanic cloud as test for stellar evolutionary models 
    Sagar, R; Subramaniam, A (Universidad Nacional Autonoma de Mexico, 1999)
    A comparison of the colour-magnitude diagrams (CMDs) and the main sequence luminosity function (LF) of five young Galactic star clusters and four young Large Magellanic Cloud star clusters derived from precise CCD observations ...
