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

Rapid formation of icy super-earths and the cores of gas giant planets
TL;DR: In this article, a coagulation model that leads to the rapid formation of super-Earths and the cores of gas giant planets is described, and it is shown that superEarths form more frequently than gas giants in low-mass disks.

TL;DR: In this paper, the authors used an empirical power-law approach to the distribution of dust and then model the production and removal of dust by means of collisions, direct radiation pressure, and drag forces.

Debris disk size distributions: steady state collisional evolution with P-R drag and other loss processes
TL;DR: In this article, a new scheme for determining the shape of the size distribution, and its evolution, for collisional cascades of planetesimals undergoing destructive collisions and loss processes like Poynting-Robertson drag is presented.
