Particle simulations are carried out to study density features caused by small moonlets embedded in a dense planetary ring. The creation of a “propeller” like structure is found together with adjacent density wakes. Both features are clear indications for the existence of moonlets in the rings. We confirmed that the propeller scales with the Hill‐radius in radial direction whereas its azimuthal extent is determined by the ratio between the moonlet‐mass and the ring‐viscosity. Our findings bear direct implications for the analysis of the Cassini imaging (ISS) and occultation (UVIS) data: (i) for the detection of embedded larger bodies (>30 m) in Saturn's rings, and (ii) for remotely probing transport properties of the rings. The existence of a moonlet population may point to a catastrophic disruption of a parent body as a formation scenario for rings.
