  • CCD photometry of the unstudied galactic star clusters Be 10, Be 67 and To 5 
    Lata, S; Mohan, V; Pandey, A. K; Sagar, R (Astronomical Society of India, 2004-03)
    We present the broad band Johnson U BV and Cousins RI CCD photometric observations for open clusters Be 10, Be 67 and To 5. So far no photometric study of these clusters is published. The colour-magnitude diagrams indicate ...
  • Mass function of open clusters NGC 1857 and Czernik 25 
    Sujatha, S; Babu, G. S. D; Ananthamurthy, S (Astronomical Society of India, 2006)
    The first CCD photometric UBVRI observations of the open clusters NGC 1857 (Czernik 20, OCl 427) and Czernik 25 (OCl 493) are presented. The observations were obtained on 28 November 2003 with the 2m Himalayan Chandra ...
  • Near IR study of the young cluster NGC 2453 
    Hasan, P; Kilambi, G. C; Baliyan, K. S (Astronomical Society of India, 2001)
    In an attempt to understand early phases of stellar evolution and star formation, we have taken up the study of extremely young star clusters in the near infrared wavebands. These clusters are deeply embedded inside the ...
  • Near-infrared JH photometry of young open cluster Be 59 
    Sharma, S; Ogura, K; Pandey, A. K; Ojha, D. K; Bhatt, B. C (Astronomical Society of India, 2007)
    We present near-infrared J H photometry and optical slitless spectroscopy of stars in the field of the young cluster Be 59. The J /(J- H )colour-magnitude diagram of the cluster yields a distance modulus of (m - M )0= 10.0 ...
  • Photometric studies of intermediate and old age galactic star clusters 
    Durgapal, A. K (Astronomical Society of India, 2001)
    We present a detailed analysis of five intermediate / old age open star clusters, based on the CCD UBVRI data. We have used a new colour index parameter (CIP), which is the difference in colour index between the blue turn ...
  • UBVRI CCD photometric studies of open clusters Berkeley 15, Czernik 18 and NGC 2401 
    Sujatha, S; Babu, G. S. D; Ananthamurthy, S (Astronomical Society of India, 2004-12)
    CCD photometric observations of three open clusters Berkeley 15 (=OCl 414), Czernik 18 (=OCl 426) and NGC 2401 (=OCl 588), obtained for the first time in UBVRI filters down to V=20 mag, are presented here. They are located ...
