Turbulence is a key ingredient in the disk evolution and planet formation. However, the origin of the low level of turbulence recently observed in protoplanetary disks is not yet well understood.
The Vertical Shear Instability (VSI) is a candidate to be responsible for the hydrodynamic turbulence in the outer regions of the disk.
Via 3D global hydrodynamical simulations, we study the evolution of the VSI in an isothermal disk, with and without an embedded planet.
We post-process the outputs of the simulations to study the observability of the VSI. We produce synthetic observations of radiative transfer calculations of the gas line emission. Further, we investigate if kinematic signatures of hydrodynamical turbulence are present in our predictions, and if they are observable in the near future with ALMA.
In this talk, I will present preliminary results on this project.
