Signatures of Companion-Disc Interaction in Young Stellar Objects

The protoplanetary discs surrounding young stellar objects are the birthplace of exoplanetary systems. Understanding the evolution of these systems is key to unravelling the formation process of our own Solar system. Historically, these objects were believed to be smooth structures that dissipate within the first few million years after molecular core collapse. However more recently, observations from more advanced interferometers have reveal a rich array of sub-structure within these discs. This work makes use of these modern observations and start-of-the-art models to better understand if these disc features are generated by embedded exoplanets or sub-stellar/binary companions.
