Abstract

The young open cluster NGC 6823 is found to have a populous region of outer cluster membership extending up to 4.3 cluster radii from the cluster center. A new UBV photometry study of the cluster region indicates that many of the cluster stars in the outer region might be pre-main-sequence objects with ages considerably younger than those of other stars in the cluster. The luminosity function for the cluster stars in the inner cluster region is similar to that of the initial luminosity function. The luminosity function for the outer cluster region is also similar to the ILF but appears to have an excess of bright cluster stars.
