Long-Term Collisional Evolution of Debris Disks
IR surveys indicate that the dust content in debris disks gradually declines with stellar age. We simulated the long-term collisional depletion of debris disks around solar-type (G2 V) stars with ourExpand

Dust distributions in debris disks: effects of gravity, radiation pressure and collisions
We model a typical debris disk, treated as an idealized ensemble of dust particles, exposed to stellar gravity and direct radiation pressure and experiencing fragmenting collisions. Applying theExpand

DUst around NEarby Stars. The survey observational results
Context. Debris discs are a consequence of the planet formation process and constitute the fingerprints of planetesimal systems. Their solar system counterparts are the asteroid and Edgeworth-KuiperExpand

Impact-generated dust clouds surrounding the Galilean moons
Abstract Tenuous dust clouds of Jupiter's Galilean moons Io, Europa, Ganymede and Callisto have been detected with the in-situ dust detector on board the Galileo spacecraft. The majority of the dustExpand

The dust grain size–stellar luminosity trend in debris discs
The cross section of material in debris discs is thought to be dominated by the smallest grains that can still stay in bound orbits despite the repelling action of stellar radiation pressure. ThusExpand

Circumplanetary Dust Dynamics: Effects of Solar Gravity, Radiation Pressure, Planetary Oblateness, and Electromagnetism
Abstract We consider the motions of circumplanetary objects perturbed simultaneously by solar gravity, radiation pressure, planetary oblateness, and electromagnetic forces. Confining ourselves to theExpand

A possible architecture of the planetary system HR 8799
HR 8799 is a nearby A-type star with a debris disk and three planetary candidates, which have been imaged directly. We undertake a coherent analysis of various observational data for all knownExpand

THE DEBRIS DISK OF VEGA: A STEADY-STATE COLLISIONAL CASCADE, NATURALLY
The archetypical debris disk around Vega has been observed intensively over the past 25 years. It has been argued that the resulting photometric data and images may be in contradiction with aExpand

A dust cloud of Ganymede maintained by hypervelocity impacts of interplanetary micrometeoroids
Abstract A dust cloud of Ganymede has been detected by in situ measurements with the dust detector onboard the Galileo spacecraft. The dust grains have been sensed at altitudes below five GanymedeExpand

Disk Radii and Grain Sizes in Herschel-Resolved Debris Disks
The radii of debris disks and the sizes of their dust grains are important tracers of the planetesimal formation mechanisms and physical processes operating in these systems. Here we use aExpand
