  • Investigating kinematics and dynamics of three open clusters towards Galactic anticentre 
    Rangwal, Geeta; Yadav, R. K. S.; Bisht, D.; Durgapal, Alok; Sariya, Devesh P. (Monthly Notices of the Royal Astronomical Society, 2023-08)
    We present the intracluster kinematics and dynamics of three open clusters: NGC 1193, NGC 2355, and King 12 by incorporating kinematical and photometric data from Gaia DR3, as well as a ground-based telescope. After ...
  • Study of spatial structure and extinction of galactic star clusters 
    Rangwal, Geeta (ARIES, Nainital, 2021-04)
    Present thesis focuses on the optical photometric, astrometric and dynamical analysis of three southern namely NGC 6067, NGC 2506, IC 4651 and two northern namely King 12 and NGC 2355 galactic star clusters. These clusters ...
