9981508NishikawaThis award supports a three-year collaborative research project between Professor Ken-Ichi Nishikawa of Rutgers University in New Jersey and Professor Kazunari Shibata of Kyoto University in Japan. The researchers will be undertaking a study of integrated research on magnetic reconnection in solar corona and magnetosphere. Magnetic reconnection is widely believed to be a crucial process in solar, magnetospheric, and astrophysical plasmas, being the means by which their magnetic topologies are determined and by which energy stored in magnetic fields is released rapidly to produce such phenomena as magnetospheric storms, solar flares, and particle acceleration in astrophysical jets. Recent solar physics missions launched into space provide the ability to observe magnetic reconnection in the solar atmosphere to a degree not before possible. The goal of the U.S. and Japanese researchers is to directly compare results from particle simulations with (1) MHD simulations, (2) low dimensional dynamic models, and (3) direct observations. These studies will reveal unsolved problems in magnetosphere, solar corona, and astrophysical jets. Simulation studies for the research will require intensive computing resources, which the researchers have available to them in both countries.The project brings together the efforts of two laboratories that have complementary expertise and research capabilities. The ability to use such simulation techniques would be critical to a full understanding of the physics underlying important processes in space weather. The project advances international human resources through the participation of postdoc and graduate students. Through the exchange of ideas and technology, this project will broaden our base of basic knowledge and promote international understanding and cooperation. Results of the research will be published in international scientific journals and will also be presented at scientific meetings in the U.S. and abroad. The research will also be available on their Web site as follows: http://www.physics.rutgers.edu/~kenichi

9981508西川该奖项支持新泽西州罗格斯大学的西川健一教授和日本京都大学的柴田和成教授之间为期三年的合作研究项目。研究人员将对日冕和磁层中的磁重联进行综合研究。磁重联被广泛认为是太阳、磁层和天体物理等离子体中的一个关键过程，通过它可以确定它们的磁拓扑结构，并通过它快速释放存储在磁场中的能量，以产生磁层风暴、太阳耀斑和天体物理喷流中的粒子加速等现象。最近发射到太空的太阳物理任务提供了观察太阳大气中磁场重联的能力，达到了前所未有的程度。美国和日本研究人员的目标是直接将粒子模拟的结果与(1)MHD模拟、(2)低维动态模型和(3)直接观测结果进行比较。这些研究将揭示磁层、日冕和天体物理喷流中尚未解决的问题。这项研究的模拟研究将需要密集的计算资源，研究人员在两个国家都可以使用这些资源。该项目汇集了两个拥有互补专业知识和研究能力的实验室的努力。使用这种模拟技术的能力对于充分理解空间气象中重要过程背后的物理基础至关重要。该项目通过博士后和研究生的参与促进了国际人力资源的发展。通过思想和技术的交流，这个项目将扩大我们的基础知识基础，促进国际理解与合作。研究结果将发表在国际科学期刊上，并将在美国和国外的科学会议上公布。这项研究还将在他们的网站上公布，网址如下：http://www.physics.rutgers.edu/~kenichi
