3D Streaming Instability 1 


Evolution of the streaming instability in a 3D local disk patch (x direction is radial, y direction is azimuthal) The movie shows particle density. As the instability progresses, radial filaments form (which is absent in the 2D unstratified case) , which eventually give birth to gravitationally bound planetesimals.
