9302098 McClymont This U.S.-Argentina Program award will support the collaboration of Alexander McClymont of the University of Hawaii at Manoa and Marta Rovira of the Instituto de Astronom a y F sica del Espacio in Buenos Aires, Argentina. The project aims to understand the mechanism of gradual magnetic energy dissipation in active regions and the physical conditions required to trigger the impulsive release of energy that produces solar flares. The physical mechanisms responsible for heating solar flares and active regions are not yet understood. Energy is thought to originate from the magnetic field in both cases, but the release mechanisms must be quite different. Heating of the active region atmosphere is quasi-steady, whereas energy is released impulsively in flares. In this project, the researchers will conduct an integrated study of magnetic energy release in the solar corona, combining both theoretical studies and the analysis of observational data. Both the U.S. and Argentine sides will benefit from the interaction of participating theorists and data analysts who share an interest in the dynamics and energetics of flares and active regions. ***

这项美国-阿根廷项目将支持夏威夷大学马诺阿分校的Alexander McClymont和阿根廷布宜诺斯艾利斯太空科学研究所的Marta Rovira的合作。该项目旨在了解活动区域磁场能量逐渐耗散的机制，以及触发产生太阳耀斑的能量脉冲释放所需的物理条件。负责加热太阳耀斑和活动区的物理机制尚不清楚。在这两种情况下，能量都被认为来自磁场，但释放机制肯定大不相同。活动区大气的加热是准稳定的，而能量在耀斑中是脉冲释放的。在这个项目中，研究人员将结合理论研究和观测数据分析，对日冕中的磁能释放进行综合研究。美国和阿根廷双方都将受益于参与的理论家和数据分析师的互动，他们对耀斑和活跃区域的动力学和能量学都感兴趣。＊＊＊
