Abstract

This research examines two largely unstudied open clusters: King 13 and Teutsch 1. It analyses their photometric and kinematic properties. The study utilizes the optical wavelength data from Gaia DR3. We found 521 and 414 candidates for their respective clusters as highly probable astrometric members. Fitting King’s profile within RDPs, we estimate both core and limiting radii. For each cluster, we create color-magnitude diagrams (CMDs) and analyses them by fitting them with appropriate isochrones that have specific metallicities (0.0193 and 0.0196) and different ages (0.818 ± 0.043 and 0.539 ± 0.038; age by Gyr), thus, the heliocentric distances are 3.00 ± 0.10 kpc, 3.885 ± 0.225 kpc for King 13 and Teutsch 1, respectively. Furthermore, 39 stragglers were identified in two clusters. In addition, the total mass (MC) in solar mass units (M⊙) may be deduced with MLR of 1522.580 and 956.136, and LF concluded that the average absolute magnitudes (MG) are 5.121 and 6.533 for respective clusters. The overall mass function corresponds to the slopes (α) for Salpeter’s value (2.35) within the uncertainty. Specifically, King 13 = 2.152 ± 0.339 and Teutsch 1 = 2.309 ± 0.870.

The current investigation and the examination of the cluster’s dynamics at various time intervals indicate that the clusters have reached a state of dynamic relaxation, with a dynamical evolution parameter of τ ≫ 1. Finally, according to a kinematical analysis, we have obtained that the coherent convergent point (A,D) is (- 116.387o,- 56.447o; King 13) and (106.607o,- 28.571o; Teutsch 1).
