Planets shepherding material into a narrow ring around Fomalhaut

Particles in the dust ring are kept inside the ring by gravitational interactions with planets. The faster-moving inner planet transfers energy to dust particles, moving them outward, deeper into the ring. The slower-moving outer planet removes energy from the particles, causing them to drop inward.
