| contents | <p>This upload contains a two-paper series presenting a coherence-based framework for quantifying organized structure in astrophysical systems through a dimensionless measure called coherence density (ρ_c).</p> <p><strong>Paper I: Coherence Density and Gradient Dynamics in Astrophysical Systems: Definition, Governing Equation, and Boundary Predictions</strong> Defines ρ_c by integrating magnetic, gravitational, thermal, and rotational observables into a canonical dimensionless metric, then derives the RMAχτ Gradient Invariant — a first-order differential law governing how ρ_c evolves spatially under suppression, regeneration, and entropy recycling. Validated against the near-Earth suppression potential and heliospheric boundary location (~122 AU, consistent with Voyager measurements). Includes worked examples spanning planets, moons, and a dwarf planet, and introduces a coherence-based reframing of habitability assessment. This paper consolidates and supersedes the original Papers I and II of the three-paper series (Zenodo: 10.5281/zenodo.18165641).</p> <p><strong>Paper II: Galactic Coherence Gradients: Empirical Validation of the RMAχτ Invariant in the Milky Way</strong> Applies the gradient law to Milky Way stellar density data, demonstrating that the same dynamics governing planetary coherence boundaries reproduce galactic-scale equilibrium structure. The equilibrium threshold is identified at 7.8 ± 0.4 kpc with 82% statistical closure across parameter space.</p> <p>Together these papers form a continuous theoretical arc: Definition + Dynamics (ρ_c and RMAχτ) → Empirical Validation (Galactic Gradients).</p> <p>Each paper can be read independently, but the set is designed as a cohesive two-part work. Readers of the original three-paper series should note that Papers I and II have been consolidated into the new Paper I, with canonical dimensionless ρ_c now the authoritative formulation throughout.</p> |
