Multi-Wavelength Modelling of the Beta Leo Debris Disc: 1, 2 or 3 planetesimal populations?
L. J. Churcher, M. C. Wyatt, G. Duchêne +7
In this paper we present a model of the Beta Leo debris disc, with an emphasis on modelling the resolved PACS images obtained as part of the Herschel key programme DEBRIS. We also…
Asymmetric Heating of the HR 4796A Dust Ring Due to Pericenter Glow
Margaret Moerchen, Laura Churcher, Charles Telesco +3
We have obtained new resolved images of the well-studied HR 4796A dust ring at 18 and 25 microns with the 8-meter Gemini telescopes. These images confirm the previously observed sp…
Resolved Imaging of the HD191089 Debris Disc
Laura J. Churcher, Mark C. Wyatt, Rachel Smith
Two thirds of the F star members of the 12 Myr old Beta Pictoris Moving Group (BPMG) show significant excess emission in the mid-infrared, several million years after the expected…
Collisional evolution of eccentric planetesimal swarms
M. C. Wyatt, M. Booth, M. J. Payne +1
Models for the steady state collisional evolution of low eccentricity planetesimal belts identify debris disks with hot dust at 1AU, like eta Corvi and HD69830, as anomalous since…
Resolved debris disk emission around eta Tel: a young Solar System or ongoing planet formation?
R. Smith, L. J. Churcher, M. C. Wyatt +2
60% of the A star members of the 12 Myr old beta Pictoris moving group (BPMG) show significant excess emission in the mid-infrared, several million years after the proto-planetary…
