论文摘要
在现场测量星际冠状动脉质量射血（ICME）组成，包括重离子的元素丰度和电荷状态，开辟了研究冠状质量弹出（CME）的新途径，除了远程感应观察结果。由于第一个电离电位（FIP）效应，不同元素丰度之间的比率可以诊断CME的血浆起源（例如，从电晕或色球球/光球）诊断出来，这意味着具有不同FIP的元素在Photosphere和Corona之间被分馏。特定元素的不同电荷状态之间的比率可以由于冻结效应而在电晕中提供CME的电子温度，可用于研究其喷发过程。在这篇综述中，我们首先概述了ICME组成，然后证明了他们在研究与CME相关的一些重要主题时的应用，例如丝状等离子体的起源和磁通量的喷发过程。最后，我们指出了一些重要的问题，应该进一步解决，以更好地利用ICME组成来研究CME。
In situ measurements of interplanetary coronal mass ejection (ICME) composition, including elemental abundances and charge states of heavy ions, open a new avenue to study coronal mass ejections (CMEs) besides remote-sensing observations. The ratios between different elemental abundances can diagnose the plasma origin of CMEs (e.g., from the corona or chromosphere/photosphere) due to the first ionization potential (FIP) effect, which means elements with different FIP get fractionated between the photosphere and corona. The ratios between different charge states of a specific element can provide the electron temperature of CMEs in the corona due to the freeze-in effect, which can be used to investigate their eruption process. In this review, we first give an overview of the ICME composition and then demonstrate their applications in investigating some important subjects related to CMEs, such as the origin of filament plasma and the eruption process of magnetic flux ropes. Finally, we point out several important questions that should be addressed further for better utilizing the ICME composition to study CMEs.
