Evolution of the Alfvén wings during the wing-wing interaction. The time range goes from t = 2.7 h to 6.0 h. We show the evolution with the example of δv_φ. The color bar is set to a range of ±38 km s⁻¹, which is about half the maximum disturbance. The planets are indicated by blue dots that represent their actual size. See the online movie for details of the interaction and a comparison between δv_φ and δp.
