SUMMARY:Debris disk imaging and evolution - Greaves\, J (St Andrews)
DTSTART:20091109T113000Z
DTEND:20091109T122000Z
UID:TALK21392@talks.cam.ac.uk
CONTACT:Mustapha Amrani
DESCRIPTION:I will discuss imaging of debris discs over the last twenty ye
 ars\, in particular in the optical (scattered light) and submillimetre (th
 ermal emission). Resolved images contain much information about the distri
 bution of dust and so the locations of the parent comet belts and any pert
 urbing planets. Some surprising results have emerged recently on the ensem
 ble of dusty discs of nearby stars\, that help to place the Solar System i
 n context. I will discuss the time history of debris\, in particular wheth
 er mature systems (Gyr ages) can remain very dusty.
