Variable stars in the young open cluster IC 4996.
Abstract
The brightest stars of the cluster IC 4996 have been monitored for variability. These observations have led to the discovery of a new β Cephei multiperiodic variable star, lying outside the so-called "instability strip". Another member star shows variations in a longer time scale, which could be due to binarity.
