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

2.13 – Comets
TL;DR: Comets are surviving members of a formerly vast distribution of solid bodies that formed in the cold regions of the solar nebula and escaped incorporation into planets and ejection from the solar system and most have been stored in two distant reservoirs, the Oort cloud and the Kuiper belt as discussed by the authors.

A WISE View of IRAS Debris Disks: Revising the Dust Properties
TL;DR: In this article, the authors used more sensitivity data of Wide-Field Infrared Survey Explorer (WFI) to better characterize the sample stars: for the stars with IRAS detection at 60 $\mu$m only, they refit the excessive flux densities and obtain the dust temperatures and fractional luminosities; while for the remaining stars with multi-bands IRAS detections, the dust properties are revised which show that the dust temperature was over estimated in high temperatures band before.

Mid-Infrared Imaging of Two Circumstellar Disks: the cases ofHD 179218 and Epsilon Eridani.
TL;DR: In this article, a 3-D radiative transfer model of the continuum emission of the protoplanetary disk using the code RADMC3D was proposed, based on a disk with a gap to fit the observational spectral energy distribution and the radial brightness profile of HD 179218 at 12.5 μm.
