太阳第二光谱的磁敏感性

The Magnetic Sensitivity of the Second Solar Spectrum

J. Trujillo Bueno

摘要:

本文回顾了一些发展,在过去的10年里,让我们去破译的物理起源的第二个太阳光谱的几个神秘的功能,发现未知方面的太阳的隐藏的磁性通过复杂的辐射转移建模。第二个太阳光谱是太阳大气层原子和分子中辐射诱导的量子相干性的观测特征。磁场通过汉勒效应产生部分退相干,从而在出射谱线偏振中产生迷人的可观察效应。有趣的是,这些效应使我们能够“看到”磁场,而在现有仪器的限制下,塞曼效应是看不到的。在未来的几年里,对Hanle效应和Zeeman效应共同作用所产生的谱线偏振观测的物理解释可能会导致我们对太阳磁场的经验理解的新革命。

英文摘要:

This paper reviews some of the developments that over the last 10 years have allowed us to go from deciphering the physical origin of several of the enigmatic features of the second solar spectrum to discovering unknown aspects of the Sun's hidden magnetism via sophisticated radiative transfer modeling. The second solar spectrum is the observational signature of radiatively induced quantum coherences in the atoms and molecules of the solar atmosphere. Magnetic fields produce partial decoherence via the Hanle effect, giving rise to fascinating observable effects in the emergent spectral line polarization. Interestingly, these effects allow us to "see" magnetic fields to which the Zeeman effect is blind within the limitations of the available instrumentation. In the coming years, the physical interpretation of observations of the spectral line polarization resulting from the joint action of the Hanle and Zeeman effects might lead to a new revolution in our empirical understanding of solar magnetic fields.
