Anu-3600 Framework: Statistical Validation of Resonance Lattices in Exoplanetary Systems

This dataset and report present the Anu-3600 framework, a composite metric for detecting non-random orbital resonance structure in exoplanet systems. The framework computes S = 0.6R + 0.3C + 0.1A, where: R measures resonance closeness to small-integer orbital ratios (m/n ≤ 7/7), C aligns events to a 3600-year lattice (anchored to transit mid-times where available, else discovery year), A combines mean eccentricity (quantile-normalized) and transit-timing variation (TTV) flags. Using ~26,000 adjacent planet pairs from the NASA Exoplanet Archive (PS & PSCompPars tables, August 2025), the Anu-3600 framework yields: Observed weighted median S ≈ 0.635 Monte Carlo p ≈ 0.003 (N=300 shuffles) Accuracy: ~100th percentile vs null distribution (i.e., stronger than 99+% of randomized outcomes) Robustness checks include: Ablation: S outperforms R-only while preserving significance Alternative null models: circular shift p ≈ 0.003; within-system shuffle (ultra-conservative) p ≈ 1 Out-of-sample validation: train (<2024) p ≈ 0.003; test (≥2024) p ≈ 0.003 Strengthened inputs: transit-anchored C and eccentricity+TTV anomaly A confirm stability This constitutes the first public validation of the Anu-3600 framework as a statistically defensible detector of resonance lattice structure in planetary system architectures.
