  • CCD photometry of galactic open star clusters - V. King 7 
    Durgapal, A. K; Pandey, A. K; Mohan, V (Astronomical Society of India, 1997)
    CCD observations of the open cluster King 7 and two nearby fields have been made in the UBVRI passbands down to V ~ 20.0 mag. From the colour-colour diagram the reddening is estimated to be 1.25mag. Comparison of the ...
  • CCD Photometry of the Open Cluster BE 69 
    Pandey, A. K; Durgapal, A. K; Bhatt, B. C; Mohan, V; Mahra, H. S (International Astronomical Union, 1996)
    The morphological features of CMDs of Be 69 are better understood in terms of convective overshooting.The Comparison of CMDs with the convective overshoot models (Bertelli et al. 1994)produces a good fit for metallicity ...
  • CCD photometry of the open cluster King 5 
    Durgapal, A. K; Pandey, A. K; Mohan, V (Astronomical Society of India, 1998)
  • 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 ...
  • A photometric study of the open cluster King 7 
    Durgapal, A. K; Mohan, V; Pandey, A. K; Mahra, H. S (Astronomical Society of India, 1996)
  • Seeing and microthermal measurements near Devasthal top 
    Stalin, C. S; Sagar, R; Pant, P; Mohan, V; Kumar, B; Joshi, Y. C; Yadav, R. K. S; Joshi, S; Chandra, R; Durgapal, A. K; Uddin, W (Astronomical Society of India, 2001)
    Results of the seeing measurements carried out near Devasthal top on 43 nights during March to April 1999 are presented. Open air seeing measurements were carried out with a differential image motion monitor (DIMM) using ...
  • Site characterization for the UPSO-TIFR telescope 
    Sagar, R; Uddin, W; Pandey, A. K; Stalin, C. S; Mohan, V; Sanwal, B. B; Gupta, S. K; Yadav, R. K. S; Durgapal, A. K; Joshi, S; Kumar, B; Gupta, A. C; Joshi, Y; Srivastava, J. B; Chaubey, U. S; Singh, M; Pant, P; Gupta, K. G; Padalia, T. D (Astronomical Society of India, 2000)
    The Uttar Pradesh State Observatory, Naini Tal and Tata Institute of Fundamental Research, Mumbai plan to install jointly a 3 metre size optical telescope at Devasthal located east of Naini Tal about 50 km by road. The ...
  • Stellar contents of the open clusters Be 64 and Be 69 
    Pandey, A. K; Durgapal, A. K; Bhatt, B. C; Mohan, V; Mahra, H. S (EDP Sciences, 1997-04)
    We present UBVRI CCD photometry for previously unstudied open clusters (Be 64 and Be 69). Photometry has also been carried out for nearby fields to correct for the effects of field stars contamination. From the colour-colour ...
