The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) XII. Constraints on large bodies embedded in discs

M. R. Jankovic, A. V. Krivov, T. D. Pearce +17

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) presents detailed constraints on structure and properties of a sample of 24 debris discs at millimetre wavelengths, i…

The effect of sculpting planets on the steepness of debris-disc inner edges

Tim D. Pearce, Alexander V. Krivov, Antranik A. Sefilian +6

Debris discs are our best means to probe the outer regions of planetary systems. Many studies assume that planets lie at the inner edges of debris discs, akin to Neptune and the Ku…

The clumpy structure of Eridani's debris disc revisited by ALMA

Mark Booth, Tim D. Pearce, Alexander V. Krivov +8

Eridani is the closest star to our Sun known to host a debris disc. Prior observations in the (sub-)millimetre regime have potentially detected clumpy structure in the disc and…

Using debris disk observations to infer substellar companions orbiting within or outside a parent planetesimal belt

T. A. Stuber, T. Löhne, S. Wolf

Aims. We analyze whether the effects of secular perturbations, originating from a substellar companion, on the dust dynamics in a debris disk can be investigated with spatially res…

Collisions and drag in debris discs with eccentric parent belts

T. Löhne, A. V. Krivov, F. Kirchschlager +2

Context: High-resolution images of circumstellar debris discs reveal off-centred rings that indicate past or ongoing perturbation, possibly caused by secular gravitational interact…

The Inner 25 AU Debris Distribution in the epsilon Eri System

Kate Y. L. Su, James M. De Buizer, George H. Rieke +6

Debris disk morphology is wavelength dependent due to the wide range of particle sizes and size-dependent dynamics influenced by various forces. Resolved images of nearby debris di…

Collisional modelling of the AU Microscopii debris disc

Ch. Schüppler, T. Löhne, A. V. Krivov +6

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…

Absorption of crystalline water ice in the far infrared at different temperatures

Caroline Reinert, Harald Mutschke, Alexander Krivov +2

The optical properties of ice in the far infrared are important for models of protoplanetary and debris disks. In this report we derive a new set of data for the absorption (repres…

Debris disc formation induced by planetary growth

Hiroshi Kobayashi, Torsten Loehne

Several hundred stars older than 10 million years have been observed to have infrared excesses. These observations are explained by dust grains formed by the collisional fragmentat…

Will New Horizons see dust clumps in the Edgeworth-Kuiper belt?

Christian Vitense, Alexander V. Krivov, Torsten Löhne

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 gian…

Potential multi-component structure of the debris disk around HIP 17439 revealed by Herschel/DUNES

S. Ertel, J. P. Marshall, J. -C. Augereau +16

[abridged] Aims. Our Herschel Open Time Key Programme DUNES aims at detecting and characterizing debris disks around nearby, sun-like stars. In addition to the statistical analysis…

Herschel's "Cold Debris Disks": Background Galaxies or Quiescent Rims of Planetary Systems?

A. V. Krivov, C. Eiroa, T. Löhne +24

(abridged) Infrared excesses associated with debris disk host stars detected so far peak at wavelengths around ~100μm or shorter. However, six out of 31 excess sources in the Hersc…

DUst Around NEarby Stars. The survey observational results

C. Eiroa, J. P. Marshall, A. Mora +47

Debris discs are a consequence of the planet formation process and constitute the fingerprints of planetesimal systems. Their solar system's counterparts are the asteroid and Edgew…

A peculiar class of debris disks from Herschel/DUNES - A steep fall off in the far infrared

S. Ertel, S. Wolf, J. P. Marshall +21

Aims. We present photometric data of debris disks around HIP 103389 (HD 199260), HIP 107350 (HN Peg, HD206860), and HIP 114948 (HD 219482), obtained in the context of our Herschel…

An improved model of the Edgeworth-Kuiper debris disk

Christian Vitense, Alexander V. Krivov, Hiroshi Kobayashi +1

(Abridged) We access the expected EKB dust disk properties by modeling. We treat the debiased population of the known transneptunian objects (TNOs) as parent bodies and generate th…

A Herschel resolved far-infrared dust ring around HD 207129

J. P. Marshall, T. Löhne, B. Montesinos +26

Dusty debris discs around main sequence stars are thought to be the result of continuous collisional grinding of planetesimals in the system. The majority of these systems are unre…

The cold origin of the warm dust around epsilon Eridani

Martin Reidemeister, Alexander V. Krivov, Christopher C. Stark +3

Context: The K2V star eps Eri hosts one known inner planet, an outer Kuiper belt analog, and an inner disk of warm dust. Spitzer/IRS measurements indicate that the warm dust is pre…
