We apply our recently elaborated, powerful numerical approach to the high-resolution modeling of the structure and emission of circumstellar dust disks, incorporating all relevant physical processes. Specifically, we examine the resonant structure of a dusty disk induced by the presence of one planet. It is shown that the planet, via resonances and gravitational scattering, produces (1) an asymmetric resonant dust belt with one or more clumps, intermittent with one or a few off-center cavities… Expand

Orbital Motion of Resonant Clumps in Dusty Circumstellar Disks as a Signature of an Embedded Planet
We have applied a powerful numerical approach to compute, with a high resolution, the structure of dusty circumstellar disks with embedded planets. We emphasize some testable implications of ourExpand
Direct imaging of exoEarths embedded in clumpy debris disks
The inner solar system, where the terrestrial planets formed and evolve, is populated by small grains of dust produced by collisions of asteroids and outgassing comets. At visible and infraredExpand
Resonant Structures in Planetesimal Disks due to Planetary Migration
Context. The observed clumpy structures in debris disks are commonly interpreted as particles trapped in mean-motion resonances with an unseen exo-planet. Populating the resonances requires aExpand
A planetary system as the origin of structure in Fomalhaut's dust belt
TLDR
The sharp inner edge and offset demonstrate the presence of planetary-mass objects orbiting Fomalhaut, demonstrating the structure of a dusty disk modified by the gravitational influence of planets. Expand
A dynamical simulation of the debris disk around HD 141569A
We study the dynamical origin of the structures observed in the scattered-light images of the resolved debris disk around HD 141569A. The disk has two conspicuous spiral rings and two large-scaleExpand
A symmetric inner cavity in the HD~141569A transitional disk
Some circumstellar disks, called transitional or hybrid disks, present characteristics of both protoplanetary disks (significant amount of gas) and debris disks (evolved structures around youngExpand
Dust in the solar system and in extra-solar planetary systems
Among the observed circumstellar dust envelopes a certain population, planetary debris disks, is ascribed to systems with optically thin dust disks and low gas content. These systems containExpand
Dynamics of Small Bodies in Planetary Systems
The number of stars that are known to have debris disks is greater than that of stars known to harbor planets. These disks are detected because dust is created in the destruction of planetesimals inExpand
On the Observability of Giant Protoplanets in Circumstellar Disks
We investigate the possibility of detecting giant planets that are still embedded in young circumstellar disks. On the basis of models with different stellar, planetary, and disk masses and differentExpand
Detection and Characterization of Extrasolar Planets through Mean-Motion Resonances. II. The Effect of the Planet's Orbital Eccentricity on Debris Disk Structures
Structures observed in debris disks may be caused by gravitational interaction with planetary or stellar companions. These perturbed disks are often thought to indicate the presence of planets andExpand
