The work addresses why some scattered-disk objects have unusually large perihelion distances that keep them detached from strong scattering by Neptune. It highlights a pathway where capture in Neptune mean-motion resonances enables Kozai (Lidov–Kozai) oscillations that trade inclination for eccentricity, lifting perihelia while preserving resonant protection. This coupling provides a dynamical explanation for producing long-lived, high-perihelion orbits from the scattered disk, informing how we interpret the origin and stability of detached trans-Neptunian populations.
