The Solar Photospheric Abundance of Iron
Abstract
A new value of the solar photospheric abundance of iron, independent of line-shape parameters, is derived. Our analysis is based on a study of 40 weak infrared lines (0.85<λ<2.5 μ) for which theoretical oscillator strengths (calculated with configuration interactions taken into account) have recently been computed by Kurucz (1974). The abundance obtained, AFe = 7.57±0.11 (in the usual scale where log NH = 12.00) is in agreement with the `high' solar values recently reported in the literature and with the meteoritic abundance.
