Context. Recent progress in the seismic interpretation of field Cep stars has resulted in improvements of the physics in the stellar structure and evolution models of massive stars. Further asteroseismic constraints can be obtained from studying ensembles of stars in a young open cluster, which all have similar age, distance and chemical composition. Aims. To improve our comprehension of the Cep stars, we studied the young open cluster NGC 884 to discover new B-type pulsators, besides the two known Cep stars, and other variable stars.
