Gaia photometric and kinematics studies of fouropen star clusters: King 13, Juchert-Saloranta 1,Teutsch 1, and Teutsch 5

Abstract This paper presents the results of the studying photometric, and kinematics offour open star clusters; namely King 13, Juchert-Saloranta 1, Teutsch 1, andTeutsch 5 utilizing the most recent data of Gaia EDR3. The most probable ofthe star members was computed using the ASteCA code and the numbers ofmembers of the clusters (N); (521) King 13, (429) Juchert-Saloranta 1, (414)Teutsch 1, and (191) Teutsch 5. The parameter structure of each object suchas cluster radii range from 3.00 to 7.00 arcmin. We obtained the distance fromSun 3.000±0.100 kpc, 4.891±0.554 kpc, 3.885±0.225 kpc, and 2.979±0.167 kpc,respectively. The values of age 0.818±0.043 Gyr, 0.9754±0.123 Gyr, 0.539±0.038Gyr, and 0.899±0.159 Gyr, respectively. The kinematical parameters have beencomputed; The position of the cluster convergent is computed by the AD diagrammethod, cluster velocity, center of the cluster, elements of solar motion, and spacevelocity components.
