Abstract
The solar photospheric abundance of silicon is derived from application of theoretical oscillator strengths for transition arrays of the type 3 pns −3 pn′p in Si 1 and 4 s −4 p in Si II. The two stages of ionization are in agreement and lead to log N (Si) = 7.55 on the scale where log N (H) = 12.00. We discuss the interpretation of the profiles of strong Si 1 lines and suggest a modification of the solar model atmosphere. The [Si 1] line at 10991.41 Å is found to be only a minor contributor to a blend with a telluric line.Keywords
