Abstract

The situation with the reliability of calculations of the magnetic field of the solar corona remains a topic of discussion. There is, in particular, the problem of significantly lower calculated values of the magnetic field than those recorded near the Earth. The authors propose an explanation in which the magnetic fields are underestimated due to the existence of magnetic sources at different distances from the photosphere. Sources that are farther away from the photosphere create local zones of weaker photospheric fields, which are not accurately measured against strong fields from sources of another level. Model estimates of the contributions of sources showed that sources located closer to the photosphere give only 30% of the total contribution of sources of both levels. This value corresponds to the observed ratio of the calculated values of the magnetic field and recorded in the solar wind. This fact confirms the assumption that the magnetic fields of sources farther from the photosphere are not really taken into account in the calculations of the magnetic field of the solar corona.

磁场产生过程在太阳电晕中的表现

摘要

太阳日冕的磁场计算的可靠性问题仍然是讨论的话题。特别地，存在磁场的计算值远低于在地球附近记录的磁场的计算值的问题。作者提出了一种解释，其中由于距光球不同距离的磁场的存在，磁场被低估了。距离光球较远的源会创建较弱的光球场的局部区域，无法相对于来自另一个级别的源的强场进行精确测量。模型对辐射源贡献的估计表明，靠近光球的辐射源仅占两个水平辐射源总贡献的30％。该值对应于观察到的磁场计算值的比率，并记录在太阳风中。这一事实证实了这样的假设，即在计算日冕的磁场时，并未真正考虑到距离光球较远的源的磁场。
