Vortensity normalized by the initial vortensity in rϕ coordinates for a ±100 au zoom-in to panel b of Fig. 5. The overdensity appears as a region of lower vortensity compared to its surroundings indicating that it is indeed a vortex. The orbits of the planets are shown as dotted green lines and the location of each planet is indicated by a small green cross symbol.
