Can eccentric debris disks be long-lived? A first numerical investigation and application to Reticuli
V. Faramaz, H. Beust, P. Thébault +13
Imaging of debris disks has found evidence for both eccentric and offset disks. One hypothesis is that these provide evidence for massive perturbers that sculpt the observed struct…
An independent determination of Fomalhaut b's orbit and the dynamical effects on the outer dust belt
Hervé Beust, Jean-Charles Augereau, Amy Bonsor +7
The nearby star Fomalhaut harbours a cold, moderately eccentric dust belt with a sharp inner edge near 133 au. A low-mass, common proper motion companion (Fom b), was discovered ne…
Herschel Observations of Debris Discs Orbiting Planet-hosting Subgiants
Amy Bonsor, Grant M. Kennedy, Mark C. Wyatt +2
Debris discs are commonly detected orbiting main-sequence stars, yet little is known regarding their fate as the star evolves to become a giant. Recent observations of radial veloc…
An interferometric study of the Fomalhaut inner debris disk. III. Detailed models of the exozodiacal disk and its origin
J. Lebreton, R. van Lieshout, J. -C. Augereau +15
[Abridged] Debris disks are extrasolar analogs to the solar system planetesimal belts. The star Fomalhaut harbors a cold debris belt at 140 AU as well as evidence of a warm dust co…
The short-lived production of exozodiacal dust in the aftermath of a dynamical instability in planetary systems
Amy Bonsor, Sean Raymond, Jean-Charles Augereau
Excess emission, associated with warm, dust belts, commonly known as exozodis, has been observed around a third of nearby stars. The high levels of dust required to explain the obs…
Spatially Resolved Images of Dust Belt(s) Around the Planet-hosting Subgiant Kappa CrB
Amy Bonsor, Grant M. Kennedy, Justin R. Crepp +4
We present Herschel spatially resolved images of the debris disc orbiting the subgiant Kappa CrB. Not only are these the first resolved images of a debris disc orbiting a subgiant,…
