Abstract: Here we present a 450 μm image of Fomalhaut's debris disk taken with SCUBA at the JCMT. The increased resolution over previous 850 μm images permits the detection of a clump embedded in the disk containing 5% of the total flux. Clumps are also a common feature of other debris disks. We discuss the origin of these clumps in the light of a tentative observation that clump mass remains constant with disk age.
