Abstract

We present a statistical and multiwavelength photometric studies of young open cluster IC 1590. We identified 91 cluster members using GaiaGaia DR3 astrometry data using ensemble-based unsupervised machine learning techniques. From GaiaGaia EDR3 data, we estimate the best-fitted parameters for IC 1590 using the Automated Stellar Cluster Analysis package (ASteCA) yielding the distance dd \sim 2.87 ±\pm 0.02 Kpc, age \sim 3.54 ±\pm 0.05 Myr, metallicity zz \sim 0.0212 ±\pm 0.003, binarity value of \sim 0.558, and extinction AvA_v \sim 1.252 ±\pm 0.4 mag for an RvR_v value of \sim 3.322 ±\pm 0.23. We estimate the initial mass function slope of the cluster to be α\alpha = 1.081 ±\pm 0.112 for single stars and α\alpha = 1.490 ±\pm 0.051 for a binary fraction of \sim 0.558 in the mass range 1 M_{\odot} \leq m(M_{\odot}) \leq 100 M_{\odot}. The GG-band luminosity function slope is estimated to be \sim 0.33 ±\pm 0.09. We use (JH)(J-H) versus (HKs)(H-K_s) color-color diagram to identify young stellar objects (YSOs). We found that all the identified YSOs have ages \leq 2 Myr and masses \sim 0.35 - 5.5 M_{\odot}. We also fit the radial surface density profile. Using the galpy we performed orbit analysis of the cluster. The extinction map for the cluster region has been generated using the PNICER technique and it is almost similar to the dust structure obtained from the 500 μ\mumm dust continuum emissions map of HerschelHerschel SPIRE. We finally at the end discussed the star formation scenario in the cluster region.
