Three-body models of dust dynamics suggest that extrasolar planets can create significant resonant structures in exozodiacal clouds and other debris disks. These structures are a worrisome source of confusion for missions that aim to directly detect extrasolar planets. So far, most models of these resonant structures have focused on Neptune- and Jupiter-mass planets. However, our simulations suggest that, under the right conditions, terrestrial-mass planets can also create high-contrast structures. Using a custom tailored hybrid symplectic integrator on the 420-node Thunderhead cluster at Goddard Space Flight Center, we have performed many simulations of 25,000 particles each in an effort to catalog these structures. The models incorporate a realistic size distribution of particles and include enough particles to overcome the limitations of previous simulations that were often dominated by a handful of long-lived particles. These high-fidelity simulations allow us to confidently predict the contrast in the resulting ring structures.
