Study of clusters in the star forming region G174+2.5

We study the structure, photometric diagrams and kinematics of four embedded clusters (S235North-West, S235A-B-C, S235Central and S235East1+East2) in the star-forming region associated with the giant molecular cloud G174+2.5. This research uses photometric data from the GPS UKIDSS catalog and astrometric data from the Gaia DR3 catalog. We determine the center positions, radii, and interstellar extinction for clusters in the region. An extinction was determined in two ways --- using the NICEST algorithm and the Q-method. The latter method gives a smaller scatter of the color indices on the extinction-corrected photometric diagrams. The membership probability of stars in the clusters, their masses and distances to clusters are also estimated. Additionally, we determine the average proper motions and study the kinematics of the clusters using data from the Gaia DR3 catalog. In all four regions, we estimate the mass of the gas component and the efficiency of star formation. Then, we apply the data obtained to evaluate the total energy of both the stellar and gas systems. It allows us to ascertain whether the clusters are gravitationally bound or not. The boundness of the systems depends on the size of the region where we estimate the mass of gas. If we take the mass of the entire cloud, all four cluster-gas systems appear to be gravitationally bound.
