SUMMER 2002 PHOTOMETRIC MULTISITE CAMPAIGN ON THE OPEN CLUSTER NGC 6633

摘要

NGC 6633 is a solar metallicity, young open cluster. In addition to providing useful information from an as-teroseismic point of view, it has the additional attractiveness of being located in the potential field of view of the COROT space mission (indeed, it is currently included in the primary target selection list). We report on some preliminary results from a multisite photometric monitoring campaign intended to search for variability in NGC 6633. The detection of δ Scuti stars is a determining factor in the choice of this open cluster as target of the COROT Seismology program. We report the detection of new δ Scuti stars together with other types of pulsating variables (γ Doradus, SPB, Ap stars, etc.) and some binary systems.
