论文摘要
了解太阳大气中的许多物理过程需要确定每个大气层中的磁场。但是，很难获得太阳电场中磁场的直接测量。使用与冠状动脉多通道极化计的观测，我们确定了电晕中血浆密度的空间分布，以及等离子体中现行的横向磁性流动力波的相位速度。我们将这些测量结果结合在一起，以绘制全局冠状磁场的天际平面成分。 Corona的派生场强度从1.05到1.35太阳半径大部分是1-4高斯。这些结果证明了成像光谱在冠状磁场诊断中的能力。
Understanding many physical processes in the solar atmosphere requires determination of the magnetic field in each atmospheric layer. However, direct measurements of the magnetic field in the Sun's corona are difficult to obtain. Using observations with the Coronal Multi-channel Polarimeter, we have determined the spatial distribution of the plasma density in the corona, and the phase speed of the prevailing transverse magnetohydrodynamic waves within the plasma. We combine these measurements to map the plane-of-sky component of the global coronal magnetic field. The derived field strengths in the corona from 1.05 to 1.35 solar radii are mostly 1-4 Gauss. These results demonstrate the capability of imaging spectroscopy in coronal magnetic field diagnostics.
