SHINE: Determining the Role of Ideal Instabilities in the Initiation of Coronal Mass Ejections (CMEs) Through Multiwavelength Observations

提出建议的团队将量化日冕物质抛射（cme）和太阳灯丝喷发中扭动运动的作用，并研究这种运动在引发喷发或改变其随后演变过程中可能发挥的作用。这是由首席研究员（PI）和他的合作者最近的工作所激发的，他们支持这样一种观点，即细丝轴的扭曲可能是细丝喷发的驱动因素，并且可以定义喷发的性质。在他们的分析中，提议团队将使用夏威夷莫纳罗亚太阳天文台（MLSO）和加州大熊太阳天文台（BBSO）的高节奏地面观测数据，以及几个航天器的数据。特别是，MLSO仪器将允许多普勒速度判别，并提供独特的诊断能力，以确定扭动运动与强度数据相结合。预期的结果将提高我们对CME爆发起源的认识，并为精确模拟CME的起源和演化提供必要的输入。这项研究将直接支持青年科学家和研究生的发展和指导，并将为至少一篇博士论文做出贡献。这项研究的结果也将被纳入PI在莱斯大学的本科讲座课程，并将通过莱斯大学的本科研究项目为学生提供研究机会的基础。PI还将利用莱斯大学的“世纪学者”计划（该计划与教师合作，为顶尖新生提供导师）招募两名新的学者（他的招聘重点是代表性不足的学生群体）。提案人将提供向公众宣传的机会，把他们的科学成果纳入“太阳周”教育网站http://www.solarweek.org，该网站是由PI创建的，旨在鼓励中学女生从事科学事业。

The proposing team will quantify the role of writhing motions in coronal mass ejections (CMEs) and solar filament eruptions and examine the role such motions might play in either initiating the eruption or modifying its subsequent evolution. This is motivated by recent work by the principal investigator (PI) and his collaborators that supports the idea that writhe of the filament axis is a possible driver of filament eruptions and could define the nature of the eruption. In their analysis, the proposing team will use high cadence, ground-based observations from the Mauna Loa Solar Observatory (MLSO) in Hawaii and Big Bear Solar Observatory (BBSO) in California, along with data from several spacecraft. MLSO instrumentation, in particular, will allow for Doppler velocity discrimination and provide a unique diagnostic capability for determining writhing motions in conjunction with intensity data. The expected results should improve our understanding of the initiation of CME eruptions and provide the necessary input for accurate modeling of the initiation and evolution of CMEs.This research will directly support the development and mentoring of young scientists and graduate students, and will contribute to at least one PhD thesis. The results of this research will also be incorporated into the PI's undergraduate lecture courses at Rice University, and will provide a basis for student research opportunities through Rice's undergraduate research program. The PI will also make use of Rice's "Century Scholars" program (which partners faculty as mentors for top-tier freshmen) to recruit two new Scholars (with his recruiting focus on under-represented student populations). The proposers will provide public outreach opportunities by inclusion of their science results into the "Solar Week" educational web site at http://www.solarweek.org, which was created by the PI to encourage middle school girls to pursue careers in science.
