Collisions that remove particles from the (s = 0.93 µm, e = 0.35, q = 102 au) bin at T = 100 Myr in the Reference (left) and Zodi runs (right). The vertical and horizontal axes are the pericenter distance q and size s of the grains that collide with grains in that bin, respectively. Colors represent the collisional rates. These rates are summed over all collision partner’s eccentricities, and the numbers in the bins represent the eccentricity of the projectile with the highest collision rate. Bins where the collision with the projectile with the highest collision rate is disruptive or cratering are hatched while the ones where it is rebounding are not.
