Centaur minimum semimajor axis of initially hot TNOs as a function of T (and I_∞) for semimajor axes 50 ≤ a (au) ≤ 140 (solid curves) inside the stable region, and a = 40, 200, 500 au (dashed curves) outside the stable region. The color codes are those of Figs. 3 and 5. The average semimajor axis, ⟨a_min⟩, and standard deviation, σ_a, are shown in the top and bottom panels, respectively.
