SIMBAD data

HD 206267 is a triple star. It lies in the nebula IC 1396. All three components are large and powerful blue stars, and the intense ultraviolet radiation they give off ionizes the gas of IC 1396, and causes compression denser globules of the nebula, leading to star formation. The stellar wind produced by the stars is strong enough to strip nearby stars of their protoplanetary disks.
