标题： Ion Charge States from a Global Time-Dependent Wave-Turbulence-Driven Model of the Solar Wind: Comparison with in-situ Measurements

摘要： 太阳风电荷态测量包含了与它们起源的日冕特性相关的丰富知识。 然而，它们的解释仍然具有挑战性，因为这将日冕温度、密度和速度沿着粒子穿过日冕的轨迹进行了卷积，在它们“冻结”并被输运到太阳风中之前。 在本研究中，我们通过将非平衡电离模型与日冕和内日球的全球磁流体动力学模型相结合，计算离子电荷态。 我们展示了两个代表太阳活动极小期和极大期的时期的结果，并与ACE探测器的观测结果进行了比较。 我们发现，该模型再现了观测结果的基本特征，纠正了早期一维计算中出现的不一致之处，并使我们能够明确地追踪电荷态从日冕底部到太阳风中的演化过程。 显示英文摘要

摘要： Solar wind charge-state measurements contain a wealth of knowledge related to the properties of the solar corona from where they originated. However, their interpretation has remained challenging because it convolves coronal temperature, density, and velocity along the particles' trajectory through the corona before they ``freeze in'' and are convected outward through the solar wind. In this study, we calculate ion charge states by coupling a non-equilibrium ionization model with a global magnetohydrodynamic model of the corona and inner heliosphere. We present results for two periods characteristic of solar minimum and maximum and compare them with observations from the ACE spacecraft. We find that the model reproduces the essential features of the observations, rectifying an earlier inconsistency that was apparent in 1-D calculations, and allows us to unambiguously trace the evolution of charge states from the base of the corona into the solar wind.
