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

High spatial resolution imaging of thermal emission from debris disks
TL;DR: In this article, the authors obtained subarcsecond mid-IR images of a sample of debris disks within 100 pc. For their sample of 19 A-type debris disk candidates chosen for their IR excess, they have resolved, for the first time, five sources plus the previously resolved disk around HD 141569 and two other sources in their sample have been ruled out as debris disks since the time of sample selection.

Planetesimal-driven migration as an explanation for observations of high levels of warm, exozodiacal dust
TL;DR: In this paper, the authors use N-body simulations to show that the outwards migration of a planet into a belt, driven by the scattering of planetesimals, can increase, or sustain, the rate at which planetesims are scattered from the outer belt to the exozodi region.

Direct imaging and spectroscopy of a young extrasolar kuiper belt in the nearest ob association
Thayne Currie,Carey M. Lisse,Marc J. Kuchner,Nikku Madhusudhan,Scott J. Kenyon,Christian Thalmann,Joseph C. Carson,John H. Debes +7 more
TL;DR: In this paper, the authors describe the discovery of a bright, young Kuiper belt-like debris disk around HD 115600, a ∼1.4-1.5 M{sub ⊙, ∼15 Myr old member of the Sco-Cen OB Association.

TL;DR: In this paper, a new planet candidate was discovered on direct images around the young (10-17 Myr) A-type star HD 95086, and the strong infrared excess of the system indicates that, similar to HR8799, Beta Pic, and Fomalhaut, the star harbors a circumstellar disk.
