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

SMACK: A New Algorithm for Modeling Collisions and Dynamics of Planetesimals in Debris Disks
TL;DR: The Superparticle Model/Algorithm for Collisions in Kuiper belts and debris disks (SMACK) as discussed by the authors is a new method for simultaneously modeling, in 3D, the collisional and dynamical evolution of planetesimals in a debris disk with planets.

Near-infrared emission from sublimating dust in collisionally active debris disks
TL;DR: In this article, the authors investigated whether pile-ups still occur when collisions are taken into account, and if they can explain the observed near-infrared (NIR) emissions emanating from the innermost parts of some debris disks.

The short-lived production of exozodiacal dust in the aftermath of a dynamical instability in planetary systems
TL;DR: In this article, the authors used a database of N-body simulations to investigate the aftermath of dynamical instabilities between giant planets in systems with outer planetesimal belts, and found that, whilst there is a significant increase in the mass of material scattered into the inner regions of the planetary system following an instability, this is a short-lived effect.
