Quantized Stellar Ages: The Plasma Resonant Constant Governs the Age Distribution of Solar-Type Stars in the Solar Neighbourhood

Two independent datasets — the Geneva-Copenhagen Survey (13,241 FGK dwarfs) and Kepler asteroseismic catalogs (483 stars, median age uncertainty ±0.34 Gyr) — show that the age distribution of G-type dwarfs is significantly non-uniform (KS statistic 4.5× above p=0.05 threshold). Five peaks in the Kepler distribution correspond to PRC harmonic ages with ε < 0.5%. The spectral-type peak shift (G0–G4 peaks at 5.5–7.0 Gyr, G5–G9 peaks at 7.5–11.0 Gyr) cannot be explained by star formation history or selection effects, but is uniquely predicted by κ = π × φ × α.
