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

Searching for Biosignatures in Exoplanetary Impact Ejecta
Gianni Cataldi,Alexis Brandeker,Philippe Thebault,Kelsi N. Singer,Engy Ahmed,Bernard L. de Vries,Anna Neubeck,Göran Olofsson +7 more
TL;DR: This work aims to investigate the possibility of characterizing an exoplanet by studying material ejected from the surface during an impact event, and considers the possibility to constrain the dust composition, giving information on the geology or the presence of a biosphere.

White Dwarf Planetary Systems: Insights Regarding the Fate of Planetary Systems
Amy Bonsor,Siyi Xu +1 more
TL;DR: In this article, the authors track the accretion of dusty planetary material in disks that share many similarities with Saturn's rings, as well as proto-planetary disks, and show that rocky planetary material similar in composition to bulk Earth is common, and that differentiation and collisions play a key role in planetary systems.

Dynamical Heating Induced by Dwarf Planets on Cold Kuiper Belt-like Debris Disks
TL;DR: In this article, the authors study the evolution and orbital behavior of cometary nuclei in cold Kuiper belt-like debris disks under the gravitational influence of dwarf planets (DPs), with and without the presence of a Neptune-like giant planet.
