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

Disk evolution in the solar neighborhood - I. Disk frequencies from 1 to 100 Myr
TL;DR: In this paper, the authors studied the evolution of circumstellar disks in 22 young (1 to 100 Myr) nearby (within 500 pc) associations over the entire mass spectrum using photometry covering from the optical to the mid-infrared.

Eccentric planets and stellar evolution as a cause of polluted white dwarfs
Shane Frewen,Brad M. S. Hansen +1 more
TL;DR: In this article, the authors examined the possibility of a single planet as the source of pollution and showed that a planet must be eccentric (e > 0.02) to deliver significant (> 0.5 per cent) amounts of material to the host and the amount increases with the planetary eccentricity.

High-temperature water–rock interactions and hydrothermal environments in the chondrite-like core of Enceladus

TL;DR: It is suggested that high reaction temperatures (>50 °C) are required to form silica nanoparticles whether Enceladus' ocean is chemically open or closed to the icy crust, which implies either that Ence Gladus formed shortly after the formation of the solar system or that the current activity was triggered by a recent heating event.
Journal ArticleDOI
Origin and Evolution of the Cometary Reservoirs
TL;DR: Brasser et al. as mentioned in this paper proposed the Nice model, in which the giant planets formed closer together than they are now, and underwent a dynamical instability that led to a flood of comets and asteroids throughout the Solar System.

The history of the Solar system's debris disc: observable properties of the Kuiper belt
Mark Booth,Mark C. Wyatt,Alessandro Morbidelli,Amaya Moro-Martin,Amaya Moro-Martin,Harold F. Levison +5 more
TL;DR: In this article, the authors investigated the infrared emission from the Kuiper belt during the history of the solar system as described by the Nice model and found that the Solar system would have been amongst the brightest of these systems before the LHB at both 24 and 70 μm.
