A Comparative Study of the Streaming Instability: Unstratified Models with Marginally Coupled Grains
The episode discusses a comparative study of seven hydrodynamic simulations investigating the nonlinear saturation phase of streaming instability in unstratified protoplanetary disks. The hosts conclude that while the general growth sequence is consistent, quantitative differences between particle-based and fluid dust models at moderate resolutions are significant, requiring higher resolution for convergence.
