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结合起来，并用最先进的FIP（第一电离势）效应模型对其进行扩展。这为我们提供了一个自我一致地预测太阳风成分的模型，包括快速和慢速太阳风的FIP分值。利用标准的源面弹道反向映射技术，我们将能够将这些模型结果与ACE/-（高级成分探测器）和Ulysses/SWICS （ACE和Ulysses上的太阳风离子成分光谱仪）以及SOHO/CELIAS（太阳日光层天文台的电荷、元素和同位素分析系统）的太阳风成分测量结果联系起来，并得出FIP效应变化与各自太阳源区的相关性结论。

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.
