View from above of the same simulation as in Fig. 1, but with an initial eccentricity of ec = 0.2 for the additional planet TWA 7 c. This configuration reproduces the observed inner edge of the disk but fails to preserve a stable population of horseshoe co-orbitals along the orbit of TWA 7 b, leaving only two separate arcs consisting of particles moving on tadpole orbits.
