Spirals, rings, gaps and asymmetries: using disc structure to infer planet formation processes

We have recently entered an era of high resolution, spatially resolved observations of protoplanetary discs, which are revealing exciting disc structures. Such structures give us clues on the protoplanetary disc and planet formation processes. I will discuss some of the causes of spirals, rings, gaps and asymmetries in protoplanetary discs. I will also discuss the possible processes that are causing the spirals in the Elias 2-27 disc, and will show how we might observationally determine if a planet is migrating.
