Abstract : Star clusters are the group of stars that are formed around the same time but have different masses. Here, we use the Gaia DR3 data of stars in young star forming regions to identify cluster members and perform kinematic and structural studies to link them with the star formation processes. The Gaussian Mixture Model (GMM) is used for the probabilistic identification of cluster members. The identified cluster members are then used for the kinematic and structural study of the clusters. The color Magnitude Diagrams (CMD) generated were then fitted against the PARSEC isochrone models using a quantitative fitting method to determine their age, metallicity, distance, and extinction. Transverse velocity and its dispersion were estimated to evaluate its survival in the Galactic tidal field. The Kernel Density Diagrams (KDE) were used to trace the structure of the cluster. The membership information, kinematics, and structure of young star clusters will be used to throw light on the processes of star formation that shape up these observed cluster properties.
