Paschen部分回归
Paschen is Partially Back
摘要：
本文讨论了磁性Ap星的部分Paschen-Back（PB）效应。概述了理论的例子说明如何分裂偏离非线性从简单的塞曼图片，通常禁止“鬼线”出现在强磁场。由此产生的不对称恒星斯托克斯配置文件的偶极磁几何所示的FeII 6149线，它是建立PB线可能会受到波长漂移。在PB制度中的斯托克斯轮廓建模打开了令人兴奋的新诊断。
英文摘要：
We present a discussion of the partial Paschen-Back (PB) effect in magnetic Ap stars. An overview of the theory is illustrated with examples of how splittings deviate non-linearly from the simple Zeeman picture; normally forbidden ``ghost lines'' appear in strong fields. Resulting asymmetric stellar Stokes profiles for a dipolar magnetic geometry are shown for the FeII 6149 line and it is established that PB lines may be subject to wavelength shifts. Modelling of Stokes profiles in the PB regime opens exciting new diagnostics.
