Together with @sijme-jan.bsky.social we continue to look at dust instabilities in planet forming discs when considering many dust sizes (polydisperse). This time we probe the Dust Settling Instability (DSI) via hydro simulations in a local box

Nonlinear Evolution of the Unstratified Polydisperse Dust Settling Instability
Context. The Dust Settling Instabilty (DSI) is a member of the Resonant Drag Instabilities (RDI) family, and is thus related to the Streaming Instability (SI). Linear calculations found that the unstr...
