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

Impact of the initial disk mass function on the disk fraction
TL;DR: In this article, the authors investigated the relationship between the decay timescale of the disk fraction and the mass dissipation timescales of an individual disk, and they showed that if the disk mass decreases exponentially, the time variation in the disk fractions depends on the spread of the DMF and the detection threshold of a disk.

Serpentinization in the Thermal Evolution of Icy Kuiper Belt Objects in the Early Solar System
TL;DR: In this paper , an improved algorithm is presented to model the serpentinization process in planetesimals in the early solar system, based on the model by Góbi & Kereszturi and contains improvements in the consideration of heat capacities and lithospheric pressure and in the calculation of the amount of interfacial water.

Can the dustiest main sequence stars tell us about the rocky planet formation process
TL;DR: In this article, the authors examined some of the dustiest main sequence stars known and three processes that may be capable of reproducing their observed properties, and made an estimate for the likelihood of an A-type star to have an asteroid belt-like planetesimal population.

Carl-Henrik Dahlqvist,Julien Milli,Olivier Absil,Faustine Cantalloube,Luca Matrà,Elodie Choquet,C. del Burgo,Jonathan P. Marshall,Mark C. Wyatt,Steve Ertel +9 more
TL;DR: In this article , a set of H-band images taken by the VLT/SPHERE instrument in the context of the SHARDDS survey were used to detect and characterise potential exoplanets and brown dwarfs within debris disks.
