Collisional Grooming of Debris Disks

TL;DR

This paper introduces a new 3D modeling approach for debris disks that self-consistently includes grain collisions, enhancing understanding of disk structures influenced by planets.

Contribution

It presents a novel steady-state 3D model that incorporates grain-grain collisions in debris disks, addressing a gap in previous models.

Findings

Collisions significantly affect debris disk structures.

Resonant trapping interacts with collisions in complex ways.

Models show how planetary perturbations shape disk features.

Abstract

Debris disk images show clumps, rings, warps, and other structures, many of which have been interpreted as perturbations from hidden planets. But so far, no models of these structures have properly accounted for collisions between dust grains. We have developed new steady-state 3D models of debris disks that self-consistently incorporate grain-grain collisions. We summarize our algorithm and use it to illustrate how collisions interact with resonant trapping in the presence of a planet.
