Planetesimal Belts in Misaligned Wide Stellar Binaries
… companion on a misaligned wide orbit perturbs planetesimals to high eccentricities. First, in order to explain the mys- terious light-curve of KIC 8462852, one component of a wide binary star system in the Kepler field with deep, irregular and aperiodic dips in its light-curve, a Monte Carlo …

The Structure of Extrasolar Planetesimal Belts in Images
Solid bodies in the form of planets and planetesimal belts familiar to us in the Solar System are also a prevalent feature around other stars. Their great diversity highlights a lack of complete theories for how they formed, which is further complicated by observational challenges to understand …

High-resolution studies of exoplanetesimal belt formation and evolution
… within the protoplanetary system: planets, and belts of planetesimals (km-sized rocky and icy bodies). Planetesimals within belts readily collide and produce detectable levels of dust and gas, known as debris discs, around 20% of main sequence stars. Despite the ubiquity of planets and …

Dust disks around hot white dwarfs and central stars of planetary nebulae
… mechanisms are: (1) breakup of bodies in planetesimal belts through collisions, (2) formation of circumstellar dust disks through binary interactions. In addition, we have derived basic dust disk parameters using simple blackbody approximations, or optically thin dust disk models with …
