The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) XI: Gas-dust interactions and radial offsets between micron and millimetre-sized grains

J. Olofsson, M. R. Jankovic, S. Marino +22

The dust observed in debris disks is the result of a collisional cascade initiated from km-sized parent bodies. Using near-infrared to sub-millimeter observations, we can pr…

How hard is dust in debris disks?

Tobias Stein, Alexander V. Krivov, Torsten Löhne

Observational appearance of debris disks is largely controlled by collisional grinding of their dust grains. However, the mechanical strength of dust at sizes in the micrometer to…

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS). X. Interpreting the peculiar dust rings around HD 131835

M. R. Jankovic, N. Pawellek, J. Zander +27

Dusty discs detected around main-sequence stars are thought to be signs of planetesimal belts in which the dust distribution is shaped by collisional and dynamical processes, inclu…

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) I: Motivation, sample, data reduction, and results overview

S. Marino, L. Matrà, A. M. Hughes +39

The outer regions of planetary systems host dusty debris discs analogous to the Kuiper belt (exoKuiper belts), which provide crucial constraints on planet formation and evolution p…

Self-gravity of debris discs can strongly change the outcomes of interactions with inclined planets

Pedro P. Poblete, Torsten Löhne, Tim D. Pearce +1

Drastic changes in protoplanets' orbits could occur in the early stages of planetary systems through interactions with other planets and their surrounding protoplanetary or debris…

Relating grain size distributions in circumstellar discs to the spectral index at millimetre wavelengths

Torsten Löhne

The excess emission seen in spectral energy distributions (SEDs) is commonly used to infer the properties of the emitting circumstellar dust in protoplanetary and debris discs. Mos…

Impact of planetesimal eccentricities and material strength on the appearance of eccentric debris disks

Minjae Kim, Sebastian Wolf, Torsten Löhne +2

Context: Since circumstellar dust in debris disks is short-lived, dust-replenishing requires the presence of a reservoir of planetesimals. These planetesimals in the parent belt of…

Debris Disc Constraints on Planetesimal Formation

Alexander V. Krivov, Aljoscha Ide, Torsten Löhne +2

Two basic routes for planetesimal formation have been proposed over the last few decades. One is a classical "slow-growth" scenario. Another one is particle concentration models, i…

Origin and evolution of two-component debris discs and an application to the q Eridani system

Christian Schüppler, Alexander V. Krivov, Torsten Löhne +3

Many debris discs reveal a two-component structure, with an outer Kuiper-belt analogue and a warm inner component whose origin is still a matter of debate. One possibility is that…

Collisional modelling of the debris disc around HIP 17439

Ch. Schüppler, T. Löhne, A. V. Krivov +3

We present an analysis of the debris disc around the nearby K2 V star HIP 17439. In the context of the Herschel DUNES key programme the disc was observed and spatially resolved in…

Debris disc candidates in systems with transiting planets

Alexander V. Krivov, Martin Reidemeister, Simone Fiedler +2

Debris discs are known to exist around many planet-host stars, but no debris dust has been found so far in systems with transiting planets. Using publicly available catalogues, we…

The Debris Disk of Vega: A Steady-State Collisional Cascade, Naturally

Sebastian Müller, Torsten Löhne, Alexander V. Krivov

It has been argued that the photometric data and images of the archetypical debris disk around Vega may be in contradiction with the standard, steady-state collisional scenario of…

On the nature of clumps in debris disks

Alexander V. Krivov, Martina Queck, Torsten Löhne +1

The azimuthal substructure observed in some debris disks, as exemplified by epsilon Eridani, is usually attributed to resonances with embedded planets. In a standard scenario, the…
