标题： An Insight into the Coupling of CME Kinematics in Inner and Outer Corona and the Imprint of Source Regions

摘要： 尽管研究日冕物质抛射（CMEs）已有数年，但我们尚未完全理解它们的运动学。 在这方面，CMEs从内日冕（$<$3R$_\odot)$）到更高高度时运动学的变化是至关重要的。 我们对Majumdar等人（2020）研究的59个CMEs的多个三维运动学参数进行了后续统计研究。 这些CMEs的源区域被识别并分类为活动区（ARs）、活动暗条（APs）和暗条爆发（PEs）。 我们研究了不同运动学参数之间的统计相关性。 我们表明，平均运动学参数在从内日冕传播到外日冕时会发生变化，这表明通常进行平均的区域的重要性。 我们还发现，外日冕中的参数受到内日冕中参数的高度影响，这表明内日冕在理解运动学中的重要性。 我们进一步发现，CMEs的源区域会对不同运动学参数之间的统计相关性产生明显的影响，而整体相关性往往会掩盖这一关键信息。 这项工作的结果支持了可能不同的动力学类别对于来自活动区和暗条的CMEs，这体现在它们的运动学中。 显示英文摘要

摘要： Despite studying Coronal Mass Ejections (CMEs) for several years, we are yet to have a complete understanding of their kinematics. In this regard, the change in kinematics of the CMEs, as they travel from the inner corona ($<$ 3R$_\odot)$ to the higher heights is essential. We do a follow up statistical study of several 3D kinematic parameters of 59 CMEs studied by Majumdar et al. (2020). The source regions of these CMEs are identified and classified as Active Regions (ARs), Active Prominences (APs), and Prominence Eruptions (PEs). We study several statistical correlations between different kinematic parameters of the CMEs. We show that the average kinematic parameters change as they propagate from the inner to the outer corona, indicating the importance of the region where normally the common practice is to perform averaging. We also find that the parameters in the outer corona is highly influenced by those in the inner corona, thus indicating the importance of inner corona in the understanding of the kinematics. We further find that the source regions of the CMEs tend to have a distinct imprint on the statistical correlations between different kinematic parameters, and that an overall correlation tends to wash away this crucial information. The results of this work lends support towards possibly different dynamical classes for the CMEs from active regions and prominences which is manifested in their kinematics.
