Main characteristics of fragment 1 (left column) and fragment 2 (right column) in model 3 before the least massive of them (fragment 2) has dispersed. In particular, panel a) presents the orbital distance of the fragments, panel b) the masses of the fragments (solid lines) and masses confined within the Hill radii (dashed lines), and panel c) denotes the radii of the fragments (solid lines) and their Hill radii (dashed lines).
