N2  - Protoplanetary disks, consisting of gas and dust, are thought to be the birthplace of planets. Recent observations have revealed a multitude of substructures in the dust continuum and scattered light emission. It is unclear if these gaps, rings and asymmetries are signposts of embedded planets interacting with their surroundings, or if different physical mechanisms, such as hydrodynamic instabilities, interactions with magnetic fields and disk winds could be the origin. Observations indicate that the lifetime of protoplanetary disks is limited to several million years and it is debated whether accretion due to turbulent processes, planet-disk interaction or disk winds might be the driving factor of disk dispersal. In this work a suite of numerical (magneto-)hydrodynamical simulations of planet-disk interaction as well as photoevaporation and magnetically driven disk winds was carried out. We found that asymmetries observed in the dust continuum can indicate the presence of an embedded planet, containing several earth masses of dust. Furthermore, we found that dust can efficiently be entrained in both thermal and magnetic disk winds, being potentially observable and assisting the identification of the physics driving the wind. Extending the wind models to transition disks revealed accretion rates compatible with recent observations with a similar dependence on the disk mass.
