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)和太阳暗条喷发中的扭转运动的作用，并研究这些运动可能在启动喷发或改变其随后的演化方面所起的作用。这是由首席研究员(PI)和他的合作者最近的工作所推动的，他们支持这样的观点，即细丝轴的扭曲可能是细丝喷发的驱动因素，并可能定义喷发的性质。在他们的分析中，提出建议的团队将使用夏威夷莫纳罗亚太阳天文台(MLSO)和加利福尼亚州大熊太阳天文台(BBSO)的高节奏地面观测，以及来自几个航天器的数据。特别是，MLSO仪器将允许进行多普勒速度辨别，并为结合强度数据确定扭转运动提供独特的诊断能力。预期的结果将提高我们对CME爆发的理解，并为准确模拟CME的起源和演化提供必要的输入。这项研究将直接支持年轻科学家和研究生的发展和指导，并将有助于至少一篇博士论文。这项研究的结果还将被纳入国际和平研究所在莱斯大学的本科课程，并将为学生通过赖斯的本科生研究计划提供研究机会。PI还将利用赖斯的“世纪学者”计划(与教师合作，作为顶尖新生的导师)招募两名新的学者(他的招聘重点是代表不足的学生群体)。提倡者将通过将他们的科学成果纳入http://www.solarweek.org，的“太阳周”教育网站来提供公共推广机会，该网站是由国际学生联合会创建的，旨在鼓励中学女孩追求科学职业。

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.
