  • Some further measurements of Uranian ring condensations 
    Vasundhara, R; Bhattacharyya, J. C; Rajamohan, R; Mahra, H. S (Kluwer Academic Publishers, 1983)
    The results of photometric observations of the occultation of BD-19 degree 4222 by Uranus on April 26, 1981 from two stations in India conform with the model proposed by Elliot et al. (1981).
  • 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 ...
  • A study of the spatial variation of mass functions in some young open clusters 
    Pandey, A. K; Mahra, H. S; Sagar, R (Astronomical Society of the Pacific, 1991)
    The effect of mass segregation on cluster mass functions has been studied and it is found that the slope of the mass function is steeper in the outer parts of open dusters. Since dynamical relaxation time is always larger ...
  • 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 ...
