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, A Fe = 7.57±0.11 (in the usual scale where log N H = 12.00) is in agreement with the ‘high’ solar values recently reported in the literature and with the meteoritic abundance. |
