A Search for Collisions and Planet–Disk Interactions in the Beta Pictoris Disk with 26 Years of High-precision HST/STIS Imaging

The Astrophysical Journal
β Pictoris's well-studied debris disk and two known giant planets, in combination with the stability of the Hubble Space Telescope’s Space Telescope Imaging Spectrograph (HST/STIS) (and now also JWST), offers a unique opportunity to test planet–disk ...

Convective Overstability in Radially Global Protoplanetary Disks. I. Pure Gas Dynamics

The Astrophysical Journal
Protoplanetary disks are prone to several hydrodynamic instabilities. One candidate, convective overstability (COS), can drive radial semiconvection that may influence dust dynamics and planetesimal formation.

Massive Debris Disks May Hinder Secular Stirring by Planetary Companions: An Analytic Proof of Concept

The Astrophysical Journal
Debris disks or exo-Kuiper belts, detected through their thermal or scattered emission from their dusty components, are ubiquitous around main-sequence stars.

Energy dissipation caused by impact or slow compression of dust aggregates consisting of fibers

Progress in Earth and Planetary Science
In the process of planetesimal formation, the mechanical properties of highly porous dust aggregates play a key role. However, it has not been easy to form highly porous dust aggregates in laboratory experiments.
