The postdoctoral candidate in this case expects to soon earn her PhD from Montana State University. In collaboration with senior scientists at the University of California at Berkeley, this postdoc will use methodologies from her ongoing PhD thesis to study small solar flares that are associated with major coronal mass ejections (CMEs) using the new Minimum Current Corona (MCC) model. She will use sequences of solar magnetograms showing the photospheric magnetic field evolution of a wide variety of flare and CME events to build three-dimensional topological coronal field models that will be analyzed with the MCC model. The postdoc's goal is to test the ability of the MCC model to accurately and quantitatively predict the energy and helicity of a wide variety of eruptive solar events. She has chosen to work with the team at Berkeley's Space Sciences Laboratory because of their experience and significant contributions to research on interplanetary CMEs (ICMEs). The proposer notes that a quantitative physical understanding of the relationship between solar eruptions and ICMEs will improve space weather forecasts. This effort will therefore ultimately lead to advance warning of adverse space weather impacts and to better protection for satellite communications, navigation, and long-distance power distribution systems. This postdoctoral fellowship will broaden the representation of females in solar physics and enhance collaborations between the research groups at UC Berkeley and Montana State University.

在这种情况下，博士后候选人希望很快获得蒙大拿州立大学的博士学位。在与资深科学家在加州大学伯克利分校的合作，这个博士后将使用她正在进行的博士论文的方法来研究小太阳耀斑与主要的日冕物质抛射（CME）使用新的最小电流日冕（MCC）模型。她将使用太阳磁图序列显示各种各样的耀斑和CME事件的光球磁场演变，以建立三维拓扑日冕场模型，将与MCC模型进行分析。博士后的目标是测试MCC模型准确和定量预测各种太阳爆发事件的能量和螺旋度的能力。她选择与伯克利空间科学实验室的团队合作，因为他们的经验和对行星际CME（ICME）研究的重大贡献。提议者指出，对太阳喷发与ICME之间关系的定量物理理解将改进空间气象预报。因此，这一努力将最终导致对不利空间气象影响的预警，并更好地保护卫星通信、导航和远距离配电系统。这个博士后奖学金将扩大女性在太阳物理学中的代表性，并加强加州大学伯克利分校和蒙大拿州立大学研究小组之间的合作。
