Abstract (from CDS):

NGC 6231 is a well-studied young open cluster hosting several variable stars. In the field six β Cephei stars, several eclipsing binaries and one δ Scuti star are known (as well as a foreground δ Scuti star). In an ongoing effort to map and study the variability in NGC 6231, we present new results based on CCD time-series data optimised for the bright β Cephei stars as well as data optimised for much fainter stars. We detect 17 new variable stars in the cluster, including three δ Scuti stars, three γ Doradus candidates, three Slowly Pulsating B star candidates and one, or possibly two, new β Cephei stars.
