The Edgeworth-Kuiper belt (EKB) and its presumed dusty debris is a natural reference for extrsolar debris disks. We re-analyze the current database of known transneptunian objects (TNOs) and employ a new algorithm to eliminate the inclination and the distance selection effects in the known TNO populations to derive expected parameters of the “true” EKB. Its estimated mass is MEKB = 0.12 M⊕, which is by a factor of ∼15 larger than the mass of the EKB objects detected so far. About a half of the… Expand
An improved model of the Edgeworth-Kuiper debris disk
In contrast to all other debris disks, where the dust can be seen via an infrared excess over the stellar photosphere, the dust emission of the Edgeworth-Kuiper belt (EKB) eludes remote detectionExpand
Debris disks are thought to be sculptured by neighboring planets. The same is true for the Edgeworth-Kuiper debris disk, yet no direct observational evidence for signatures of giant planets in theExpand
Constraints on the Kuiper belt dust in the outer Solar System
The Edgeworth-Kuiper belt (EKB) and its presumed dusty debris are a natural reference for extrasolar debris disks. The dust in the EKB cannot be seen directly due to the strong foreground emission ofExpand

Abstract The dust measured in debris disks traces the position of planetesimal belts. In our Solar System, we are also able to measure the largest planetesimals directly and can extrapolate down toExpand
Near-infrared emission from sublimating dust in collisionally active debris disks
Context. Hot exozodiacal dust is thought to be responsible for excess near-infrared (NIR) emission emanating from the innermost parts of some debris disks. The origin of this dust, however, is stillExpand
Constraints on dust production in the Edgeworth‐Kuiper Belt from Pioneer 10 and New Horizons measurements
[1] Impact ejecta and collisional debris from the Edgeworth-Kuiper Belt are the dominant source of micron-sized grains in the outer solar system, as they slowly migrate inwards through the outerExpand
A peculiar class of debris disks from Herschel /DUNES
Context . The existence of debris disks around old main sequence stars is usually explained by continuous replenishment of small dust grains through collisions from a reservoir of larger objects. Expand
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
Debris disks as seen by Herschel/DUNES†
The far-infrared excesses produced by debris disks are common features of stellar systems. These disks are thought to contain solids ranging from micron-sized dust to planetesimals. Naturally, theirExpand
Collisional modelling of the AU Microscopii debris disc
The spatially resolved AU Mic debris disc is among the most famous and best-studied debris discs. We aim at a comprehensive understanding of the dust production and the dynamics of the disc objectsExpand


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
On the nature of clumps in debris disks
The azimuthal substructure observed in some debris disks, as exemplified by e Eridani, is usually attributed to resonances with embedded planets. In a standard scenario, the Poynting-Robertson force,Expand
Kuiper Belt Objects: Relics from the Accretion Disk of the Sun
▪ Abstract The Kuiper Belt consists of a large number of small, solid bodies in heliocentric orbit beyond Neptune. Discovered as recently as 1992, the Kuiper Belt objects (KBOs) are thought to holdExpand
The debris disc around τ Ceti: a massive analogue to the Kuiper Belt
An excess of far-infrared emission is seen towards the nearby G8 V star τ Ceti, and this has been attributed to orbiting dust particles generated in planetesimal collisions. A new 850-µm image showsExpand
The Insignificance of P-R drag in detectable extrasolar planetesimal belts
This paper considers a simple model in which dust produced in a planetesimal belt migrates in toward the star due to P-R drag suffering destructive collisions with other dust grains on the way.Expand
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
Collisional Time Scales in the Kuiper Disk and Their Implications
We explore the rate of collisions among bodies in the present-day Kuiper Disk as a function of the total mass and population size structure of the disk. We find that collisional evolution is anExpand
Dust production from collisions in extrasolar planetary systems. The inner beta Pictoris disc
Dust particles observed in extrasolar planetary discs originate from undetectable km-sized bodies but this valuable information remains uninteresting if the theoretical link between grains andExpand
Signatures of the Giant Planets Imprinted on the Edgeworth-Kuiper Belt Dust Disk
One method to detect extrasolar planetary systems is to deduce the perturbations of planets on the observed circumstellar dust disks. Our solar system, with its known configuration of planets,Expand
Dynamical Models of Kuiper Belt Dust in the Inner and Outer Solar System
We report several results related to the dynamical evolution of dust produced in the Kuiper belt (KB). We show that its particle size frequency distribution in space is greatly changed from theExpand
