DESCRIPTION:Speakers: Marcelo Fernando Barraza Alfaro (Max Planck Institut
 e for Astronomy\, Heidelberg)\nTurbulence is a key ingredient in the disk 
 evolution and planet formation. However\, the origin of the low level of t
 urbulence recently observed in protoplanetary disks is not yet well unders
 tood.\nThe Vertical Shear Instability (VSI) is a candidate to be responsib
 le for the hydrodynamic turbulence in the outer regions of the disk.\nVia 
 3D global hydrodynamical simulations\, we study the evolution of the VSI i
 n an isothermal disk\, with and without an embedded planet. \nWe post-proc
 ess the outputs of the simulations to study the observability of the VSI. 
 We produce synthetic observations of radiative transfer calculations of th
 e gas line emission. Further\, we investigate if kinematic signatures of h
 ydrodynamical turbulence are present in our predictions\, and if they are 
 observable in the near future with ALMA.\nIn this talk\, I will present pr
 eliminary results on this project.\n\nhttps://iaus379.aip.de/event/1/contr
