New SEP-Based Solar Abundances

Abstract

The relative abundances of various elements in the solar photosphere and the solar corona are re-determined from relative abundances of solar energetic particles (SEP) in the light of revised solar spectroscopic abundances. We find excellent correlation between SEP-based abundances and spectroscopic abundances, after correcting for fractionation due to ionic charge-to-mass ratio and first ionization potential.
