Photometric study of open clusters Berkeley 96, Berkeley 97, King 12, NGC 7261, NGC 7296, and NGC 7788

TL;DR

This study presents photometric data and analysis of six open clusters, determining their ages, distances, and color excesses, and reveals mass function gaps in three of them, contributing to understanding their stellar populations.

Contribution

It provides new CCD photometry and mass function analysis for six open clusters in the Perseus arm, including the discovery of mass gaps in three clusters.

Findings

Determined ages, distances, and color excesses for six open clusters.

Revealed mass function gaps in Be 97, King 12, and NGC 7788.

Provided comprehensive photometric data combining CCD and 2MASS observations.

Abstract

The BVRcIc CCD photometry in the fields of six open clusters toward the Perseus spiral arm is presented. These data along with JHKs magnitudes taken from 2MASS catalog, have been used to determine cluster's ages, distances and color excesses. In addition, the gaps in mass function of Be 97, King 12 and NGC 7788 clusters have been revealed in mass intervals of 1.3-1.5, 1.4-1.6 and 1.5-1.7 solar masses, respectively.
