Dusty warps in the local frame: instability and fast clumping

Warps are responsible for various global disc phenomena and observational signatures and have mostly been studied using global hydrodynamical simulations. However, their role in planet formation and affecting dust instabilities is best studied in a local frame. I will present our recent efforts in modelling dusty warps in a local shearing box and show that warps can cause dust instabilities that lead to fast dust concentrations, much faster than the streaming instability.
