Bayesian characterization of the young open cluster NGC 6383 using HDBSCAN and Gaia DR3

This study focuses on determining the characteristics of the young open cluster NGC 6383. To achieve this, the HDBSCAN clustering algorithm is utilized to identify potential cluster members based on galactic coordinates, proper motions, and parallaxes from Gaia Data Release 3. Various parameters of NGC 6383, such as tidal radius, cluster radius, core radius, distance through parallax and isochrone-fitting, proper motion, age, metallicity, and relevant others, are assessed. To perform this analysis, we utilize an extension of Hamiltonian Monte Carlo, the No-U-Turn Sampler. The results of this analysis point out that NGC 6383 is a very young open cluster (∼ 2.7 − 4 Myr). Furthermore, our investigation reveals that the central binary HD 159176 is not a member of the cluster, which was not discussed in previous studies, leading to a revision of its age and other characteristics. Overall, this study contributes to a more accurate and detailed understanding of NGC 6383’s properties.
