We test the hypothesis that an embedded giant planet in the IM Lupiprotostellar disc can produce velocity kinks seen in CO line observations aswell as the spiral arms seen in scattered light and continuum emission. Weinject planets into 3D hydrodynamics simulations of IM Lupi, generatingsynthetic observations using Monte Carlo radiative transfer. We find that anembedded planet of 2-3 times the mass of Jupiter can reproduce non-Keplerianvelocity perturbations, or `kinks', in the 12CO J=2-1 channel maps. Such aplanet can also explain the spiral arms seen in 1.25mm dust continuum emissionand 1.6 micron scattered light images. We show that the wake of the planet canbe traced in the observed peak velocity map, which appears to closely followthe morphology expected from our simulations and from analytic models ofplanet-disc interaction.
