Abstract : We present the analysis from the kinematic model of the star cluster and filed stars in the LMC using Gaia DR3 data. Our study compares the residual proper motion from clusters and field stars and explores the recent LMC-SMC interaction signatures. We compared the cluster and nearby field stars and found the Root Mean Square (RMS) values for the clusters and fields to be 0.12 mas/yr and 0.068 mas/yr, respectively. We compared our observed RMS values with numerical simulations. We found the constraints for the recent LMC-SMC interaction signature, and we suggest it must have happened between 140 Myr and 200 Myr ago. This is an ongoing work; we will be presenting the results from our initial findings.
