Results of the N-body simulations on the plane (a_A/a_P, e_A) for the symmetric configuration (θ₁, θ₂) = (0, 0) and Δϖ=0 (top), (θ₁, θ₂) = (π, 0) and Δϖ=π (middle) and (θ₁, θ₂) = (π, π) and Δϖ=0 (bottom). Green circles stand for stable outcome, red triangles for an ejected asteroid, brown squares for an asteroid that hit the planet and purple diamonds for an asteroid that collided with the WD. In the background, the initial conditions with DFLI  >   15 are included and uniformly depicted by pale gray.
