The initial conditions for planet formation: Turbulence driven by hydrodynamical instabilities in disks around young stars
Wladimir Lyra, Orkan Umurhan
This review examines recent theoretical developments in our understanding of turbulence in cold, non-magnetically active, planetesimal forming regions of protoplanetary disks which…
