The quiet-Sun temperature ratio R≈2.4 equals the KL-divergence difference between a κ=2.5 distribution and its EUV and radio Maxwellian projections, satisfying ΔD_KL = (3/2)[R0 − ln R0 − 1] = (3/2) d_IS(T_eff, T_core).
SKA's higher sensitivity and bandwidth will enable fuller exploitation of radio methods for measuring CME magnetic fields and improving space weather predictions.
This paper discusses observational, calibration, and imaging requirements for solar and heliospheric science with the SKA radio telescope.
