Circumstellar Debris Disks: gas-dust and dust-planet interactions

Yanquin Wu (Univ. Toronto) - 8 May at 12:00 noon

Dusty, gas poor disks around young stars are left-overs of the much more massive protoplanetary disks. They present many puzzles: how much gas is still embedded in these disks? What are the composition of the dust grains? What causes the rings/gaps/clumps in these disks? What are the un-equivocal signatures of planets? I will present a few results from our theoretical studies that shed some lights to these questions.

The seminar will be held in 544 Campbell Hall.
