UvbyH-beta photoelectric and CCD photometry of IC 4651
An analysis of uvbyH-beta photoelectric and CCD photometry of IC4651shows a Fe/H abundance ratio of 0.23 + or - 0.02, an E(b-y) value of0.064 + or - 0.006, and an age on the system of VandenBerg (1985) of 2.4+ or - 0.2 x 10 to the 9th yr. Scatter noted in the clustercolor-magnitude diagram can be explained by binaries, nonmembers, and ablueward hook due to the hydrogen-exhaustion phase. The cluster turnoffindicates some evidence for the presence of bimodality which issuggested to be the result of nonstandard evolution near theBohm-Vitense gap.
