- Abstract
The first CCD photometric investigation of the open cluster NGC 7296 up to now was performed within the narrow band Δa photometric system, which enables us to detect peculiar objects. A deeper investigation of that cluster followed, using the standard BV R-Bessel filter set. The age and E(B - V) was determined independently to log t = 8.0 ± 0.1 and 0.15 ± 0.02, respectively by using ±a and broadband photometry. In total five Be/Ae objects and two metal-weak stars showing significant negative Δa-values as well as one classical chemically peculiar star could be identified within that intermediate age open cluster. ©2005 WILEY-VCH Verlag GmbH & Co.
