Barranco's Model of Turbulence in Protoplanetary Disks

Caption: A sequence of images showing how turbulent forces (the Coriolis Effect and vertical shear) mix up the layers of dust and gas orbiting young stars. Images depict a 2-D slice through Joseph Barranco's 3-D simulations. Deep red indicates dust-rich gas. Deep blue indicates pure gas. The simulation is based on dust and gas that is the same distance away from its star as earth is from the sun. The time interval between frames is 3.4 years.
