论文摘要
对于所有涉及天文学的人，监测和确定天体物理磁场强度的重要性很明显。众所周知的事实是，电晕磁场在太阳耀斑的起源和太空天气的变化中起着重要的作用。但是，经过多年的太阳电晕研究，仍然没有直接和连续的方法来测量和监视太阳能磁场强度。我们将在这里提出一个方案，该方案是基于对被称为磁诱导过渡的异国原子过渡类的仔细研究，以Fe $^{9+} $。在此贡献中，我们提出了该方法的第一个应用，并使用Hinode的光谱数据确定冠状场强度的值。
For all involved in astronomy, the importance of monitoring and determining astrophysical magnetic field strengths is clear. It is also a well-known fact that the corona magnetic fields play an important part in the origin of solar flares and the variations of space weather. However, after many years of solar corona studies, there is still no direct and continuous way to measure and monitor the solar magnetic field strength. We will here present a scheme which allows such a measurement, based on a careful study of an exotic class of atomic transitions known as magnetic induced transitions in Fe$^{9+}$. In this contribution we present a first application of this methodology and determine a value of the coronal field strength using the spectroscopic data from HINODE.
