abstract
Discs of gas and dust surrounding young stars are the birthplace of planets. However, direct detection of protoplanets forming within discs has proved elusive to date. We present the detection of a large, localized deviation from Keplerian velocity in the protoplanetary disc surrounding the young star HD163296. The observed velocity pattern is consistent with the dynamical effect of a two Jupiter-mass planet orbiting at a radius $\approx$ 260au from the star.

Substructures in Planet-Forming Disks with the SKAO
SKA-Mid Band 5b continuum observations at 12.5 GHz will resolve disk substructures at ~0.05 arcsec to investigate their origin and role in planet assembly.
