Circumstellar dust exists in debris disks around hundreds of main sequence stars. This dust must be continually replenished through collisions between larger planetesimals, analogous to the bodies in the Solar System's Asteroid and Kuiper belts.
I present resolved mid-infrared imaging of debris disks around three young main sequence stars: Eta Tel, HD191089 and HR4796. I also show Herschel PACS far-IR imaging of the newly resolved debris disk around Beta Leo. I have modeled these disks to constrain the state of planet formation in these systems. These diverse disks show inner holes, asymmetries from perturbing planets and evidence of self-stirring from ongoing planet formation.
