Beryllium abundances in metal-poor stars
K. F. Tan, J. R. Shi, G. Zhao
We have determined beryllium abundances for 25 metal-poor stars based on the high resolution and high signal-to-noise ratio spectra from the VLT/UVES database. Our results confirm…
Statistical equilibrium of silicon in the solar atmosphere
J. R. Shi, T. Gehren, K. Butler +2
The statistical equilibrium of neutral and ionised silicon in the solar photosphere is investigated. Line formation is discussed and the solar silicon abundance determined. High-re…
Electron density diagnostic potential of Ar XIV soft X-ray emission lines
G. Y. Liang, G. Zhao, J. L. Zeng +1
Theoretical electron density-sensitive line ratios of Ar XIV soft X-ray emission lines are presented. We found that these line ratios are sensitive to electron density…
Kinetic equilibrium of iron in the atmospheres of cool stars III. The ionization equilibrium of selected reference stars
A. J. Korn, J. Shi, T. Gehren
Non-LTE line formation calculations of Fe I are performed for a small number of reference stars to investigate and quantify the efficiency of neutral hydrogen collisions. Using the…
