NSF-CGP Fellowship: Studies of the Solar Corona Using Simultaneous Radio, X-ray and EUV Observations

9819917 Kundu该奖项提供资金支持Mukul R.马里兰州大学天文学系Kundu教授，感谢他与日本国家天文台太阳物理学部的Takashi Sakurai博士和其他科学家合作。 这项研究将使参观者有机会获得日本几个望远镜收集的极好的数据，即Yohkoh卫星上的软X射线和硬X射线望远镜以及在17和34 GHz工作的Nobeyama射电日像仪。 这些数据集将与其他相关的地基或空基数据一起用于日冕研究。 在这次合作中，美国访问者将提供他在太阳日冕研究方面的专业知识，而日本科学家将提供计算太阳黑子大气模型外推日冕磁场的理论专业知识，以及访问Yohkoh X射线数据和地面光学数据的专业知识。旨在利用日本数据的具体活动涵盖了广泛的日冕现象，包括：（1）太阳黑子本影上方的X射线发射;（2）与日冕X射线喷流有关的无线电发射;（3）活动区在耀斑产生方面的演变;（4）在极冕洞中观测到的毫米波和微波增亮;以及（5）极冕羽流爆发的微波和米波对应物。 该项目将是互惠互利的，因为合作者的互补专业知识将有助于双向交流的想法，技能和技术计划为这项研究。 该项目由国家科学基金会和日本基金会全球伙伴关系中心之间的科学奖学金计划提供支持。

9819917KunduThis award provides funds to support a 12-month research visit by Dr. Mukul R. Kundu, Department of Astronomy, University of Maryland, for collaboration with Dr. Takashi Sakurai and other scientists in the Solar Physics Division, National Astronomical Observatory of Japan. This research will provide access of the visitor to the excellent data collected by several Japanese telescopes, namely the soft X-ray and hard X-ray telescopes on the Yohkoh satellite and the Nobeyama radioheliograph operating at 17 and 34 GHz. Together with other pertinent ground-based or space-based data, these data sets will be used for studies of the solar corona. In this collaboration, the U.S. visitor will provide his expertise in solar coronal research while the Japanese scientists will provide theoretical expertise in computing extrapolated coronal magnetic fields for sunspot atmosphere modeling, as well as expertise in accessing Yohkoh X-ray data and ground based optical data.The specific activities designed to take advantage of the Japanese data cover a broad range of coronal phenomena, including (1) X-ray emission above sunspot umbrae; (2) radio emission associated with coronal X-ray jets; (3) the evolution of active regions in terms of flare productivity; (4) millimeter and microwave brightening observed in the polar coronal holes; and (5) the microwave and meterwave counterparts of the erupting polar coronal plumes. The project will be mutually beneficial because of the complementary expertise of the collaborators which will contribute to the two-way exchanges of ideas, skills, and techniques planned for this research. This project is supported under the Science Fellowship Program between the National Science Foundation and the Japan Foundation Center for Global Partnership.***
