Unveiling Planetary Signatures in Debris Disks: A Study of Resonant Structures

This study by Marc Kuchner, Sean Moran, and others investigates resonances in debris disks around stars like ε Eridani and Fomalhaut using observations from various telescopes. It analyzes limb brightening, inclinations, and disk models to shed light on planet formation theories.
