Anisotropic and mass-charge dependent energization of coronal heavy Ions by kinetic Alfven waves

both increase rapidly with heliocentric distance in 1.5-3.5 RS (RS the solar radius). In the lower corona below 1.3 RS one has δi and γi 1, and in the higher corona above 4 RS they approach the saturation values δi 0.5Ai and γi 0.9A3 Zi , where Ai is the ion mass-charge 3 i ratio in units of the proton mass-charge ratio mp /e and Zi the ion charge in units of the elementary charge e. We suggest that the KAW-based model of the anisotropic and mass-charge dependent energization not only can in reason explain the recent observations of minor heavy ions in polar coronal holes but also KAWs can be potentially important for us to understand the microphysics of the wave-particle interaction in the extended solar corona where the coronal plasma is heated and accelerated into the solar wind.
