Comparison between the hydrodynamical simulation of the system in Toci et al. (2020), who predicted a spiral accretion stream feeding planet c (left), and our observations in the F187N (middle) and F480M (right) filters. The trace of the spiral accretion stream is identified as local radial maxima in the simulation and is shown as white dots in all images. The trace of the outer arm characterized in Juillard et al. (2022) is shown with orange dots. The part of the simulated image that is affected by subtraction artifacts is masked to show the relevant part of the image.
