Evolution of Debris Disks
TLDR
In this article, a review describes the theoretical framework within which debris disk evolution takes place and shows how that framework has been constrained by observations, including infrared photometry of large numbers of debris disks, providing snapshots of the dust present at different evolutionary phases.Abstract:
Circumstellar dust exists around several hundred main sequence stars. For the youngest stars, that dust could be a remnant of the protoplanetary disk. Mostly it is inferred to be continuously replenished through collisions between planetesimals in belts analogous to the Solar System’s asteroid and Kuiper belts, or in collisions between growing protoplanets. The evolution of a star’s debris disk is indicative of the evolution of its planetesimal belts and may be influenced by planet formation processes, which can continue throughout the first gigayear as the planetary system settles to a stable configuration and planets form at large radii. Evidence for that evolution comes from infrared photometry of large numbers of debris disks, providing snapshots of the dust present at different evolutionary phases, as well as from images of debris disk structure. This review describes the theoretical framework within which debris disk evolution takes place and shows how that framework has been constrained by observations.read more

The scattering of small bodies in planetary systems: constraints on the possible orbits of cometary material
Amy Bonsor,Mark C. Wyatt +1 more
TL;DR: In this article, the authors present an analytical model to describe the process using the simplifying assumption that each particle's dynamics are dominated by a single planet at a time, and show that the scattering process can be considered as a series of three-body problems during which the Tisserand parameter with respect to the relevant planet is conserved.

The Debris Disk of Vega: A Steady-State Collisional Cascade, Naturally
TL;DR: In this article, the authors used collisional and radiative transfer codes to model the size and radial distribution of the disk material and then thermal emission of dust, and showed that the results suggest that the Vega disk observations are compatible with a steady-state collisional dust production.
