The debris disk around gamma Doradus resolved with Herschel
Hannah Broekhoven-Fiene, Brenda C. Matthews, Grant M. Kennedy +11
We present observations of the debris disk around gamma Doradus, an F1V star, from the Herschel Key Programme DEBRIS (Disc Emission via Bias-free Reconnaissance in the Infrared/Sub…
Millimeter Emission Structure in the first ALMA Image of the AU Mic Debris Disk
Meredith A. MacGregor, David J. Wilner, Katherine A. Rosenfeld +9
We present 1.3 millimeter ALMA Cycle 0 observations of the edge-on debris disk around the nearby, ~10 Myr-old, M-type star AU Mic. These observations obtain 0.6 arcsec (6 AU) resol…
A DEBRIS Disk Around The Planet Hosting M-star GJ581 Spatially Resolved with Herschel
J. -F. Lestrade, B. C. Matthews, B. Sibthorpe +17
Debris disks have been found primarily around intermediate and solar mass stars (spectral types A-K) but rarely around low mass M-type stars. We have spatially resolved a debris di…
Resolved Debris Discs Around A Stars in the Herschel DEBRIS Survey
Mark Booth, Grant Kennedy, Bruce Sibthorpe +12
The majority of debris discs discovered so far have only been detected through infrared excess emission above stellar photospheres. While disc properties can be inferred from unres…
Herschel imaging of 61 Vir: implications for the prevalence of debris in low-mass planetary systems
M. C. Wyatt, G. Kennedy, B. Sibthorpe +15
This paper describes Herschel observations of the nearby (8.5pc) G5V multi-exoplanet host star 61 Vir at 70-500micron carried out by the DEBRIS survey. These reveal emission that i…
Debris disks as signposts of terrestrial planet formation. II Dependence of exoplanet architectures on giant planet and disk properties
Sean N. Raymond, Philip J. Armitage, Amaya Moro-Martin +6
We present models for the formation of terrestrial planets, and the collisional evolution of debris disks, in planetary systems that contain multiple unstable gas giants. We previo…
