DESCRIPTION:Speakers: Geoffroy Lesur (Institute of planetology and astroph
 ysics of Grenoble/CNRS)\nThe recent developments in our understanding of t
 he chemical composition\, the ionisation equilibrium and the dynamics of p
 rotoplanetary discs has led to the conclusion that magnetised disc wind (M
 DW) are probably playing an important role in shaping the long term evolut
 ion of these objects. Most of our understanding of these winds comes from 
 global direct numerical simulations which include complex microphysics and
  which explore only a very limited subspace of parameters. Hence\, it is v
 ery difficult to draw firm conclusions about the long-term evolution of di
 scs subject to MDW. \n\nIn this contribution\, I will present a systematic
  exploration of MDW solutions\, which can then be used in secular models t
 o predict the evolution of a disc\, in a way similar to the "alpha disc" m
 odel. I will also discuss the solutions topology (top/down symmetry\, midp
 lane/surface accretion layers\, laminar stress\, etc...) which have often 
 been mis-interpreted in the literature.\n\nhttps://meetings.aip.de/event/1
