Data analysis in combination with numerical simulations of the acceleration and propagation of energetic particles in the vicinity of planetary magnetospheres

将通过观测和模拟观点的相互作用，对加速进入地球和木星磁层喷流或上游事件的高能带电粒子进行系统研究，以便得出结论，以便对它们的产生和传播有新的和更深入的见解。第一部分将包括大量选择的航天器数据的汇编和比较，第二部分是对沿磁通量管传播过程的自洽数值模拟。对地球和木星高能粒子事件的联合调查背后的想法是利用地球周围的全面数据覆盖以及木星磁层的独特特征，从而得出关于粒子的起源和加速的结论。在木星，粒子事件源于磁层，将通过将磁层内获得的数据与磁层顶外测量的数据进行比较，特别是为了研究太阳风的可能影响，来详细研究粒子的逃逸。我们的结果将提供日光层中两个位置的扩散系数，并有助于更好地理解木星作为高能粒子的来源及其传播。

Energetic charged particles accelerated into jets or upstream events at the magnetospheres of the Earth and Jupiter will be systematically studied through an interplay of observational and modelling points of view in order to arrive at conclusions that allow new and deeper insights into their generation and propagation. The first part will consist of a compilation and comparison of a larger selection of spacecraft data, the second one of self-consistent numerical simulations of the propagation process along a magnetic flux tube. The idea behind the combined investigations of energetic particle events at the Earth and Jupiter is to take advantage of the comprehensive data coverage around the Earth as well as of the unique features of the Jovian magnetosphere that allow to draw conclusions about the origin and the acceleration of the particles. At Jupiter, where particle events are of magnetospheric origin, the escape of the particles will be studied in detail by comparing data obtained within the magnetosphere with those measured close beyond the magnetopause, in particular in order to study the possible influence of the solar wind. Our results will provide the diffusion coefficients at two positions in the heliosphere and contribute to a better understanding of Jupiter as a source of energetic particles and their propagation.
