摘要:

我们量化的尺度的磁能密度的惯性范围内的太阳风湍流看到原位在1 AU相对于太阳活动。在太阳活动最大时,当日冕磁场是动态的和拓扑复杂的,我们发现自相似标度的太阳风,而在太阳活动最小时,当日冕场更有序,我们发现多重分形。这量化的太阳风签名,是直接的日冕起源,并区分它从本地MHD湍流,与定量的影响,我们的理解日冕加热的太阳风。

英文摘要:

We quantify the scaling of magnetic energy density in the inertial range of solar wind turbulence seen in-situ at 1AU with respect to solar activity. At solar maximum, when the coronal magnetic field is dynamic and topologically complex, we find self-similar scaling in the solar wind, whereas at solar mimimum, when the coronal fields are more ordered, we find multifractality. This quantifies the solar wind signature that is of direct coronal origin, and distinguishes it from that of local MHD turbulence, with quantitative implications for our understanding of coronal heating of the solar wind.
