Exploring NGC 2345: A Comprehensive Study of a Young Open Cluster through Photometric and Kinematic Analysis

We conducted a photometric and kinematic analysis of the young open cluster NGC 2345 using CCD UBV data from 2 m Himalayan Chandra Telescope, Gaia Data Release 3, Two Micron All-Sky Survey, and the Photometric All-Sky Survey data sets. We found 1732 most probable cluster members with membership probability higher than 70%. The fundamental and structural parameters of the cluster are determined based on the cluster members. The mean proper motion of the cluster is estimated to be mu alpha cos delta = -1.34 +/- 0.20 and mu delta = 1.35 +/- 0.21 mas yr-1. Based on the radial density profile, the estimated radius is similar to 12.' 8 (10.37 pc). Using color-color and color-magnitude diagrams, we estimate the reddening, age, and distance to be 0.63 +/- 0.04 mag, 63 +/- 8 Myr, and 2.78 +/- 0.78 kpc, respectively. The mass function slope for main-sequence stars is determined as 1.2 +/- 0.1. The mass function slope in the core, halo, and overall region indicates a possible hint of mass segregation. The cluster's dynamical relaxation time is 177.6 Myr, meaning ongoing mass segregation, with complete equilibrium expected in 100-110 Myr. Apex coordinates are determined as -40.degrees 89 +/- 0.12, - 44.degrees 99 +/- 0.15. The cluster's orbit in the Galaxy suggests early dissociation into field stars due to its close proximity to the Galactic disk.
