The [Zn/Fe] -- [Fe/H] trend for disk and halo stars
Y. Q. Chen, P. E. Nissen, G. Zhao
Zn abundances, derived from a model atmosphere analysis of the 6362.35 A ZnI line, are presented for 44 thin disk, 10 thick disk and 8 halo dwarf stars in the metallicity range -1.…

Sulphur abundances in disk stars: a correlation with silicon
Y. Q. Chen, P. E. Nissen, G. Zhao +1
We have performed new determinations of sulphur and silicon abundances for a sample of 26 disk stars based on high-resolution, high signal-to-noise spectra. The results indicate a…

On the Abundance of Potassium in Metal-Poor Stars
Yoichi Takeda, Gang Zhao, Yu-Qin Chen +2
Based on extensive statistical-equilibrium calculations, we performed a non-LTE analysis of the K {\sc i} 7699 equivalent-width data of metal-deficient stars for the purpose of cla…
