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

首席调查员(PI)计划调查太阳细丝喷发和日冕物质抛射(CME)是如何被触发的。这项研究将集中在为什么以及如何当新的太阳活动区(AR)出现在距离静止灯丝中间35度的大范围内时，静止灯丝频繁爆发。这种关系最早是在1952年由布鲁泽克发现的，过去的统计研究已经证实了这种关系的正确性。PI的团队将检查新的航天器数据，以寻找太阳日冕磁场之间相互作用的证据，这可以解释布鲁泽克关系。具体地说，PI的团队将使用来自太阳日球层天文台极端紫外线成像望远镜(SOHO EIT)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的证据。国际太阳物理研究所预计，这项研究将刺激开发模拟太阳喷发细丝和日冕物质抛射的新方法，这不仅将对太阳物理研究界非常有用，而且还将为社会带来实际好处。这样的结果将改善对喷发的细丝和日冕物质抛射的预报，这对空间气象业务非常重要。一名本科生将在该项目每年夏季的几个月协助计划中的数据分析。该奖项由2009年美国复苏和再投资法案(公法111-5)资助。

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).
