Event Details & Abstract: 

A key issue in modeling protostellar disks is the presence of dead zones, midplane disk regions with little turbulence. Such regions can lead to nonsteady disk evolution and outbursts. I will describe a model for the outbursts and some of its implications to models of disk turbulence. I will also discuss some issues concerning planet migration in dead zones.
