Investigation of Solar Flares with Images of Their Microwave - Emitting Sources (Atmospheric Science)

利用欧文斯谷捷频干涉仪获得的空间、光谱和时间分辨观测，研究太阳耀斑中微波辐射源的动态演化。测量的源区和光谱参数将用于对太阳耀斑模型进行定量测试。这项研究的结果将促进我们对粒子加速和粒子相互作用的理解，如果没有与太阳火焰脉冲分量相称的光谱和时间尺度上的成像，这种理解是不可能的。互动活动包括帮助发展与现有物理和天文学女性网络的联系，在冬季教授新生物理课程的一部分，以鼓励与本科生接触，以及举办关于高能太阳物理的客座讲座和研讨会。该项目进一步推动了VPW计划的目标，即：(1)为妇女提供机会，在NSF资助的工程和科学学科中发展她们的职业生涯；(2)通过提高受雇于工业、政府和学术机构的女科学家和工程师的知名度，鼓励妇女追求科学和工程事业。通过鼓励妇女参与科学，这是对国家未来科学活力的宝贵投资。

The dynamic evolution of microwave-emitting sources in solar flares will be investigated using spatially, spectrally, and temporally resolved observations obtained with the Owens Valley frequency-agile interferometer. Measured source areas and spectral parameters will be used to make quantitative tests of solar-flare models. The results of this investigation will advance our understanding of particle acceleration and particle interactions in ways that have not been possible without imaging on the spectral and temporal scales commensurate with the impulsive component of solar flames. Interactive activities include helping to develop connections to the existing network of women in physics and astronomy, teaching a section of the freshman physics course during the winter quarter to encourage contacts with undergraduate students, and presenting guest lectures and seminars in high-energy solar physics. This project furthers VPW program objectives which are (1) to provide opportunities for women to advance their careers in engineering and in the disciplines of science supported by NSF and (2) to encourage women to pursue careers in science and engineering by providing greater visibility for women scientists and engineers employed in industry, government, and academic institutions. By encouraging the participation of women in science, it is a valuable investment in the Nation's future scientific vitality.
