Description
Observations of structures in discs such as gaps and kinks give us a tantalising glimpse of possible planets forming there. Recent numerical simulations show that planets that are misaligned with respect to the protoplanetary disc may cause the disc to warp and even break into distinct planes. These effects occur even with small misalignments and are therefore likely to be reasonably common. We have performed chemical models of a disc warped by a planet and used this to predict the kinematic signatures of planet-induced warps. We highlight the most useful diagnostics, and discuss how observations can indicate the presence of a planet at various radii within a protoplanetary disc.
