Abstract

Our VLA and MERLIN radio images of the HL Tau system trace the emission from the proto-planetary disc at ultra-high resolution. A candidate proto-planet is seen at tens of AU from the star, at these long wavelengths where it stands out from the bright background disc. A simulation shows that gravitational instability within the disc is capable of forming this 10 Jupiter-mass object. Submillimetre images made recently with SCUBA-2 show that HL Tau's disc is perturbed by an interaction with XZ Tau, and this may have helped trigger disc fragmentation, in a flyby event as recent as a few thousand years ago.
