  • 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 ...
