Evolving Coronal Magnetic Structures--VLA, RATAN 600 and SOHO

PI将与俄罗斯的RATAN 600和美国的甚大阵列（VLA）合作观测太阳。他将把VLA的高时空分辨率与RATAN的宽光谱覆盖和精确偏振数据结合起来，获取日冕磁场结构和强度的信息，以及不同等离子体结构的温度和电子密度。他还将利用这些组合数据集定位热能和非热能释放的区域。最后，他将确定由日冕磁场和电流控制的强烈、缓慢变化的日冕区域的三维温度、密度和磁结构。这些发展都将为太阳活动区磁层中捕获的粒子的发射、加热和加速机制提供新的见解。

The PI will perform collaborative observations of the Sun with the Russian RATAN 600 and the Very Large Array (VLA) in the US. He will combine the high spatial and temporal resolution of the VLA with the broad spectral coverage and accurate polarization data of RATAN one- or two-dimensional scans for information on the magnetic fields' structure and strength in the corona, as well as the temperature and electron density in different plasma structures. He will also localize regions of thermal and nonthermal energy release with these combined data sets. Finally, he will determine the three-dimensional temperature, density and magnetic structure of intense, slowly-varying coronal regions controlled by coronal magnetic fields and electric currents. These developments will all provide new insights to the emission, heating and acceleration mechanisms of particles trapped within the magnetospheres of solar active regions.
