The solar abundance of germanium, deduced from two relatively unblended Ger lines, 23039.06 and 23269.50 is found to be logN(Ge) = 3.50 • 0.05 on the scale logN(H) = 12.00 in good agreement with Cameron's recent solar system abundance logN(Ge)=3.56 (on assumption logN(Si) = 7.50).

The solar abundance of tungsten

✍ Hartmut Holweger; Klaus Werner 📂 Article 📅 1982 🏛 Springer 🌐 English ⚖ 285 KB

Recent measurements of WI oscillator strengths (Obbarius and Kock, 1982) lead to a solar photospheric abundance of tungsten, loge~r = 1.06 +\_ 0.15 on the scale log~r~ -12. The solar W/Si abundance ratio, 0.32 W atoms/106 Si, coincides with that found in carbonaceous chrondrites. Implications for s

The solar abundance of beryllium

✍ John E. Ross; Lawrence H. Aller 📂 Article 📅 1974 🏛 Springer 🌐 English ⚖ 423 KB

The solar abundance of beryllium is deduced from high-resolution Kilt Peak observations of the 23130.43 and 23131.08 lines of Be II interpreted by the method of spectrum synthesis. The results are in good agreement with those previously obtained by Grevesse and by H'auge and Engvold and indicate tha

From 13 scans obtained with a double-band pass spectrograph at the Snow telescope at Mount Wilson, interpreted by the method of spectral synthesis, the abundance of gold turns out to be log [N(Au)/N(H)] + 12 = 0.70, assuming loggf= --0.57. A single line attributable to gold, 23122.79, is found in t
