SHINE: How New Active Regions Trigger Erupting Filaments and Associated Coronal Mass Ejections (CMEs)

首席研究员（PI）计划调查如何爆发太阳细丝和日冕物质抛射（cme）被触发。研究将集中在为什么和如何当一个新的太阳活动区（AR）发生在一个广泛的区域，从静止的灯丝的中间高达35日冕度频繁爆发。这种关系最早是由Bruzek在1952年注意到的，过去的统计研究已经证实了它的有效性。PI的团队将检查新的航天器数据，寻找太阳日冕磁场之间相互作用的证据，以解释布鲁泽克关系。具体来说，PI的团队将使用来自太阳日球层天文台极紫外成像望远镜（SOHO EIT）仪器的小波处理图像来研究AR如何作为静止灯丝爆发的催化剂，即使这样的灯丝距离新形成的AR相对较远。PI将分析至少50个特定事件的样本，同时专注于观察到的磁相互作用证据。PI希望这项研究能够促进新方法的发展，以模拟太阳细丝和日冕物质抛射，这不仅对太阳物理研究界非常有用，而且对社会也有实际的好处。这样的结果将改善对喷发细丝和日冕物质抛射的预测，这对空间气象操作非常重要。一名本科生将在项目每年的夏季协助计划中的数据分析。该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。

The Principal Investigator (PI) plans to investigate how erupting solar filaments and Coronal Mass Ejections (CMEs) are triggered. The research will focus on why and how quiescent filaments frequently erupt when a new solar active region (AR) occurs within a broad area up to 35 heliographic degrees from middle of the quiescent filament. This relationship was first noted by Bruzek in 1952, and past statistical studies have verified its validity. The PI's team will examine new spacecraft data for evidence of interactions among solar coronal magnetic fields that could explain the Bruzek relationship. Specifically, the PI's team will use wavelet processed images from the Solar Heliospheric Observatory Extreme-ultraviolet Imaging Telescope (SOHO EIT) instrument to investigate how an AR can serve as a catalyst for a quiescent filament to erupt, even when such a filament is relatively distant from the newly forming AR. The PI will analyze a sample of at least 50 specific events while focusing on observed evidence of magnetic interactions. The PI expects this research to stimulate the development of new approaches to modeling erupting solar filaments and CMEs, which will not only be very useful for the solar physics research community, but also provide practical benefits to society. Such results will improve forecasts of erupting filaments and CMEs, which are important for space weather operations. One undergraduate student will assist in the planned data analysis during the summer months in each year of the project.This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).
