Wave Physics-Based Explanation of the Anomalous Heating of Stellar Coronae.v2

We present a compact, testable coronal-heating framework in which MHD waves experiencepartial reflection at steep stratification (the transition region, TR), naturally seeding counter-propagating content that dissipates via phase mixing and resonant absorption. Unlike opticsanalogies, energy reflection and transmission are derived from linear MHD with proper boundaryconditions: (i) an energy-impedance formulation for sharp interfaces, (ii) WKB transmission ingraded layers, and (iii) an oblique-incidence, mode-coupling recipe (Appendix A).
