SUMMARY:Electric Heating and Angular Momentum Transport in Laminar Models 
 of Protoplanetary Disks - William Bethune (University of Tuebingen)

DESCRIPTION:Observations point toward weak levels of turbulence in protopl
 anetary disks\, and theoretical studies now focus on magneto-thermal winds
  rather than MRI turbulence as the main driver of mass accretion. Although
  MHD turbulence might be quenched\, large-scale magnetic structures may st
 ill transport angular momentum and induce substantial accretion heating in
 side the disk. Using steady-state radiative MHD models\, I examine how muc
 h stress and heat can thus be obtained in the weakly ionized parts of prot
 oplanetary disks under the assumption of a purely laminar flow.
