The main goal of this 2-year project is to improve present understanding of the Coronal Mass Ejection (CME) process by elucidating the relationship between flux emergence and CME dynamics, thus providing additional insights into the CME genesis. The study will also clarify how flux emergence contributes to the transport magnetic energy from the solar interior to the heliosphere. The 2-year research effort is focused on an undergraduate research project, thereby providing direct training with data analysis and the conduct of scientific research. Any relationships found between source-region properties of CMEs, including flux emergence and speeds of associated CMEs, should also enable improvements in space weather forecasting, which could minimize adverse impacts of CME-driven disturbances on our society. This project directly supports the Strategic Goals of the AGS Division in discovery, learning, diversity, and interdisciplinary research.

这个为期两年的项目的主要目标是通过阐明通量涌现和日冕物质抛射动力学之间的关系来改善目前对日冕物质抛射过程的理解，从而为日冕物质抛射的起源提供更多的见解。这项研究还将阐明磁通量的出现如何有助于将磁能从太阳内部输送到日光层。为期两年的研究工作集中在一个本科生研究项目上，从而提供数据分析和科学研究指导的直接培训。在日冕物质抛射的源区性质之间发现的任何关系，包括出现的通量和相关的日冕物质抛射的速度，都应有助于改进空间天气预报，从而最大限度地减少日冕物质抛射引起的扰动对我们社会的不利影响。该项目直接支持AGS司在发现、学习、多样性和跨学科研究方面的战略目标。
