The Cui-attribute Shell and Cui Coordinate: A Phase-Transition Layer at 7.8976 kpc with Langlands Gap Correspondence
Year: 2026
Type: preprint
Abstract: The Cui-attribute shell is defined as the phase-transition layer at the Galactocentric radius R_C = 7 + 2\pi/7 \approx 7.8976 kpc, corresponding to the n_c = 7 truncation of the Generalized Projection Theory. The shell thickness is fixed at \Delta R = 0.2024 kpc by the opening ratio \rho_7 = 1/8. The Cui coordinate R_C = 7.8976 kpc serves as the spatial anchor for the Langlands positive-characteristic gap to physical spacetime. Observational verification is provided by MWISP (Nature Astronomy, 2026; deviation 2.4 pc) and VERA 99 maser sources (Hirota et al. 2020; deviation 22.4 pc, 0.28\sigma_{\text{stat}}). This record archives the formal definition, derivation, and observational anchors of the Cui-attribute shell and Cui coordinate.
