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.***

9819917Kunduthis Award提供了资金，以支持马里兰大学天文学系Mukul R. Kundu博士与日本国家天文学天文台的太阳能物理学部的其他科学家Mukul R. Kundu博士和太阳理分部的其他科学家合作。 这项研究将为访客提供几个日本望远镜收集的优秀数据，即Yohkoh卫星上的软X射线和硬X射线望远镜，以及17和34 GHz的Nobeyama Radioheliograph。 这些数据集将与其他相关的基于地面或空间基数据集一起用于太阳电晕的研究。 在这项合作中，美国的访客将在太阳能冠状研究方面提供他的专业知识，而日本科学家将在计算外推冠状磁场的理论专业知识，用于黑子大气建模，以及在访问Yohkoh X射线数据和基于地面的光学数据方面的专业知识。旨在利用日本数据的特定活动。 （2）与冠状X射线喷气机相关的无线电发射； （3）在耀斑生产力方面，主动区域的演变； （4）在极性冠状孔中观察到的毫米和微波亮度； （5）爆发的极性冠状羽流的微波炉和仪表波对应物。 由于合作者的互补专业知识，该项目将是互惠互利的，这将有助于为这项研究计划的思想，技能和技术的双向交流。 国家科学基金会和日本全球合作伙伴基金会中心之间的科学奖学金计划得到了支持。***
