Self-consistent solar wind model and the emergence of the FIP effect from Alfvén waves

我们建议将现有的太阳风加速模型与日冕场模型相结合，并用最先进的FIP(第一电离势)效应模型来增强它。这给了我们一个模型，它可以自洽地预测快太阳风和慢太阳风的组成，包括它的FIP分馏。使用源表面的标准弹道反向映射技术，我们将能够将这些模型结果与ACE/-(先进成分探测器)和Ulysses/SWICS(ACE和Ulysses上的太阳风离子成分光谱仪)以及SOHO/CELIAS(太阳日光层天文台上的电荷、元素和同位素分析系统)测量的太阳风成分相关联，并得出关于FIP效应的变化与各自太阳源区域之间的关联的结论。

We propose to combine an existing solar wind acceleration model with a model for the coronal field and augment it with a state-of-the-art model of the FIP (first ionization potential) effect. This gives us a model that self-consistently predicts the solar wind composition of both fast and slow solar wind including its FIP fractionation. Using standard ballistic backmapping techniques to the source surface we will be able to relate these model results with solar wind composition measurements by ACE/-(Advanced Composition Explorer) and Ulysses/SWICS (Solar Wind Ion Composition Spectrometer on ACE and Ulysses), and SOHO/CELIAS (Charge, Element, and Isotope Analysis System on SOlar Heliospheric Observatory) and draw conclusions about the correlation of the variation of FIP effect and the respective solar source regions.
