HD166473中锂的分析
The analysis of lithium in HD166473
摘要：
对Li I 6708 A品系的6个旋转相进行了分析，这些旋转相分布于HD 166473的整个旋转周期（9.5年）。磁场模型是根据（Mathys等人，20007）的极化测量值构建的。对于每个观察到的相位，还根据考虑塞曼磁分裂的Fe II 6147 A、6149 A和Pr III 6706.7 A谱线轮廓的模拟来估计磁场的模量。通过将观察到的Li I 6708 A曲线与假设Paschen-Back分裂计算的合成曲线拟合并根据Pr III 6706.7 A线曲线估计磁场特性，获得每个相中的锂丰度。
英文摘要：
The analysis of Li I 6708A line was performed for 6 rotational phases distributed over the whole rotational period (9.5 years) of HD166473. The magnetic field model was constructed based on the polarimetric measurements from (Mathys et al. 20007). For each observed phase the modulus of the magnetic field was also estimated from simulation of the Fe II 6147A, 6149A and Pr III 6706.7A line profiles taking into account Zeeman magnetic splitting. The lithium abundance in each phase was obtained from fitting the observed Li I 6708A profile with the synthetic one calculated assuming Paschen-Back splitting and estimated magnetic field characteristics from Pr III 6706.7A line profile.
