[9.06] Photometry and Identification of Open Star Clusters in NGC 6822

O. K. Krienke (Seattle Pacific University), P. W. Hodge (University of Washington)

From past ground-based imaging and our current Hubble Space Telescope images, we have identified by eye a total of 51 candidate open clusters in the dwarf irregular galaxy, NCG 6822. Of these, 26 candidates are located on HST images with standard wide-band filters. We analyzed these photometrically to verify their reality as clusters, finding that 8 of them failed to meet our cluster criteria. Integrated photometry in B,V, and I for 10 open clusters, and in V and I for 8 additional clusters was performed. We present integrated magnitudes and colors for these clusters, derive age estimates and the cluster luminosity function, and provide comparisons to the open cluster populations of M33 and the SMC.
