Non-LTE Analysis for the Sodium Abundances of Metal-Poor Stars in the Galactic Disk and Halo
Yoichi Takeda, Gang Zhao, Masahide Takada-Hidai +3
We performed an extensive non-LTE analysis of the neutral sodium lines of Na {\sc i} 5683/5688, 5890/5896, 6154/6161, and 8183/8195 for disk/halo stars of F--K type covering a wide…
