Hitmap of pebble impacts on an equal mass binary system such that M₁ = M₂ = (M_Pluto + M_Charon)/2, shown at the top. Every pixel is a pebble falling into the system. On the x-axis the x₀ coordinate at moment of release is shown in Hill radii, while on the y-axis the initial phase orientation of the binary φ₀ in radians is depicted as illustrated in Fig. 1. The orange pixels show impacts on M₁, the brown pixels on M₂ and the beige pixels indicate ejected pebbles. The final accretion ratio ε = 1, meaning that both bodies accrete an equal flux of pebbles because of symmetry arguments. The dashed red line indicates a starting angle of φ₀ = π rad. From 6 results in this graph the trajectories have been plotted below, those are denoted as A-F in this hitmap. The resolution has been taken . Bottom panel: six trajectories from the hitmap above. Shown is a top-down view of the binary system with a pebble “falling” in. In each of the trajectories, an arrow denotes the pebble coming into the frame. Pebble trajectories A through F are sorted with their starting distance, x₀, going from left to right, corresponding to closer radial distance from the star to further away, respectively. We note that even though the trajectory for F appears to start on the bottom left, it originated on the right outside of the frame only entering the image below.
