摘要:

10倍太阳半径以下的日冕是日冕物质抛射驱动的激波对太阳高能粒子早期加速和输运的重要区域。在那里,这些波传播到一个高度可变的动态介质中,该介质具有陡峭的梯度和快速扩展的日冕磁场,这调制了冲击或波表面附近的粒子加速度,以及SEP传播到日光层的方式。我们提出了一项研究模拟的加速SEPs在全球日冕冲击事件的日冕,以及他们的运输到1 AU,望远镜观测的基础上,加上动态物理模型。

英文摘要:

The solar corona below 10 solar radii is an important region for early acceleration and transport of solar energetic particles (SEPs) by coronal mass ejection-driven shock waves. There, these waves propagate into a highly variable dynamic medium with steep gradients and rapidly expanding coronal magnetic fields, which modulates the particle acceleration near the shock or wave surfaces, and the way SEPs spread into the heliosphere. We present a study modelling the acceleration of SEPs in global coronal shock events in the corona, as well as their transport to 1 au, based on telescopic observations coupled with dynamic physical models.
