From the structure of the jet from the Herbig Ae star HD 163296 we infer that it is the result of nearly periodic (15 yr) ejection events. Iron is not depleted in the high-velocity jet, indi- cating its dust content is low. However, the photometric behavior of the central source does indicate that a significant amount of dust is episodically lifted from the disk sur- face, probably on larger radial distances and lower velocities than the atomic jet.
