Solar Wind Fractionation — Isotopic and Elemental — and Implications for Solar Compositions and Future Genesis Analyses

adsorption line strengths for selected elements. Shown are the ratios of values from Grevesse and Sauval (2002; blue) and from Asplund et al. (2009; green), both compared to values reported by Anders and Grevesse (1989) [11-13].
