Illustration of the Gamma Cas system

Caption

Gamma Cas consists of a Be-type star surrounded by a disk of material; some of this material flows toward the companion; a second disk forms around the companion, and the material eventually flows toward the poles, where it emits X-rays (green arrows). Some of these X-rays are reflected by the surface of the white dwarf (purple arrows).
