NSF-CGP Science & Engineering Fellowship Program: Studies of the Solar Corona Using Simultaneous X-ray and Radio Observations

该提案支持马里兰州大学帕克分校天文系的Mukul Kundu博士和日本三鹰国家天文台的Takashi Sakurai博士的合作。 项目资金将允许Kundu博士在日本三鹰居住6个月，以便利用日本空间使命Yohkoh和地面射电望远镜同时获得的X射线和射电观测资料研究日冕。 Kundu博士利用无线电和X射线成像数据对太阳日冕的知识做出了开创性的贡献。 樱井博士将从磁能储存和触发机制的角度，将他的理论专长带到研究太阳活动区和耀斑的问题上。 他们将共同研究一系列太阳日冕现象：研究太阳黑子上方的X射线发射，研究与日冕喷流有关的无线电发射，研究活动区域在耀斑产生方面的演变。 这一提议使两个国家从事太阳日冕物理学研究的科学家聚集在一起。 美国科学家将有机会熟悉与Yohkoh X射线技术相关的研究技术，同时为整体研究工作做出贡献。因此，该提案实现了该计划通过国际合作交流和转让科学知识的目标。

This proposal supports the collaboration of Dr. Mukul Kundu of the Department of Astronomy , University of Maryland at College Park and Dr. Takashi Sakurai of the National Astronomical Observatory, Mitaka, Japan. Project funding will permit Dr. Kundu to spend 6 months in Japan, resident in Mitaka, in order to study the sun's corona using simultaneously obtained X-ray and radio observations with the Japanese Space mission Yohkoh and ground based radio telescopes. Dr. Kundu has made pioneering contributions to the knowledge of the sun's corona using combined radio and X-ray imaging data. Dr. Sakurai will bring his theoretical expertise to the problem of studying solar active regions and flares from the point of view of magnetic energy storage and trigger mechanisms. They will jointly study a broad range of solar coronal phenomena : study of X-ray emission above sunspots, study of radio emission associated with coronal jets, study of the evolution of active regions in terms of flare productivity. This proposal brings together research scientists from two countries working in the area of solar coronal physics. The U.S. scientist will have the opportunity to become familiar with research techniques related to Yohkoh X-ray techniques while contributing to the overall research effort. Therefore this proposal fulfills the objectives of the Program in its exchange and transfer of scientific knowledge through an international collaboration.
