ATMAN v5.0 Paper X: Long-term Dynamical Stability of the Three-Perturber Outer Solar System — A 100 Myr ATMAN v5.0 Integration
Year: 2026
Type: article
Abstract: Paper X of the ATMAN v5.0 series. A 100 Myr N-body integration of the three-perturber outer Solar System (Solution B: 6M⊕, 75au; Erebo: 7M⊕, 600au; P3: 12M⊕, 1000au) using ATMAN v5.0 with dt=1000yr and 10,000 checkpoints. Both Erebo and P3 are orbitally stable over the full 100 Myr integration: Erebo maintains a=715.2±0.00au, e=0.401±0.0000; P3 maintains a=1039.9±0.00au, e=0.196±0.0000. Kuiper Cliff depletion proxy averaged over full integration: Ddep=0.602. The three-perturber architecture is dynamically viable on Solar System formation timescales. Paper X of the ATMAN v5.0 series.
