ATMAN v5.0 Paper VII: The Sedna Anomaly and a Third Trans-Neptunian Perturber — A Perihelion-Lifting Sweep with ATMAN v5.0
Year: 2026
Type: article
Abstract: Description: Paper VII of the ATMAN v5.0 series. A two-dimensional mass-distance sweep over a hypothetical third trans-Neptunian perturber P3 with M∈[1,20]M⊕ and a∈[800,2500]au, using ATMAN v5.0 with Erebo and Solution B as fixed background bodies. Three Sednoids tracked as test particles: Sedna, 2012 VP113, Leleakuhonua. Best-fit solution: MP3=12M⊕, aP3=1000au, producing ΔqSedna=+7.46au and joint score Sjoint=0.692 — highest in the series. SHA-256: 60c348fd1859e32f5bb45b4e155e4ef52f1f33c5ce823a83aaba536bc8553229. Paper VII of the ATMAN v5.0 series.
