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

提议的团队将量化日冕物质抛射（CME）和太阳灯丝爆发中扭动运动的作用，并研究这种运动在引发爆发或改变其随后的演变中可能发挥的作用。这是由首席研究员（PI）及其合作者最近的工作所激发的，该工作支持这样一种观点，即灯丝轴的扭动是灯丝喷发的可能驱动因素，并可以定义喷发的性质。在他们的分析中，提议的团队将使用来自夏威夷的莫纳罗亚太阳天文台（MLSO）和加州的大熊太阳天文台（BBSO）的高节奏地面观测数据，沿着来自几个航天器的数据。MLSO仪器，特别是，将允许多普勒速度歧视，并提供一个独特的诊断能力，确定扭动运动与强度数据。预期的结果应该提高我们的理解CME爆发的启动，并提供必要的输入CMEs的启动和演化的精确建模。这项研究将直接支持年轻科学家和研究生的发展和指导，并将有助于至少一个博士论文。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计划为学生的研究机会提供基础。PI还将利用赖斯的“世纪学者”计划（该计划与教师合作，为顶级新生提供导师）招募两名新学者（他的招募重点是代表性不足的学生群体）。提议者将通过将其科学成果纳入“太阳周”教育网站http://www.solarweek.org，提供公共宣传机会，该网站由PI创建，以鼓励中学女生从事科学职业。

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.
