Long-Term Collisional Evolution of Debris Disks
- T. Lohne, A. Krivov, J. Rodmann
- Physics
- 23 October 2007
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 our… Expand
Dust distributions in debris disks: effects of gravity, radiation pressure and collisions
- A. Krivov, T. Loehne, M. Srem̌cevíc
- Physics
- 1 August 2006
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 the… Expand
DUst around NEarby Stars. The survey observational results
- C. Eiroa, J. Marshall, +47 authors H. Walker
- Physics
- 1 May 2013
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-Kuiper… Expand
Impact-generated dust clouds surrounding the Galilean moons
- HaraldKruger, A. Krivov, Miodrag Sremvcevi'c, E. Grun
- Physics
- 22 April 2003
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 dust… Expand
The dust grain size–stellar luminosity trend in debris discs
- N. Pawellek, A. Krivov
- Physics
- 14 September 2015
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. Thus… Expand
Circumplanetary Dust Dynamics: Effects of Solar Gravity, Radiation Pressure, Planetary Oblateness, and Electromagnetism
- D. Hamilton, A. Krivov
- Physics
- 1 October 1996
Abstract We consider the motions of circumplanetary objects perturbed simultaneously by solar gravity, radiation pressure, planetary oblateness, and electromagnetic forces. Confining ourselves to the… Expand
A possible architecture of the planetary system HR 8799
- M. Reidemeister, A. Krivov, +4 authors R. Neuhauser
- Physics
- 28 May 2009
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 known… Expand
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 a… Expand
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 Ganymede… Expand
Disk Radii and Grain Sizes in Herschel-Resolved Debris Disks
- N. Pawellek, A. Krivov, +5 authors C. Eiroa
- Physics
- 17 July 2014
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 a… Expand
