A field model of the sun's inner coronal magnetic field , as observed by the Ulysses spacecraft at very high latitudes, explained 26-day recurrent energetic particle events. This project explores the consequences of a revised heliospheric magnetic field model (Fisk, 1996), including explanation of the slow solar wind, elemental abundance's in the solar wind, dynamics of pick-up ions, and cosmic ray modulation. Investigators will research the consequences on: (1) high latitude recurrent energetic particle events, (2) the propagation of cosmic rays in the heliosphere, (3) the acceleration of the solar wind, and (4) the propagation of pick-up ions in the heliosphere. Simultaneously, this investigation will test the revised model from many vantage points. The investigators hope to increase understanding of heliospheric dynamics through a deeper understanding of heliospheric magnetic field.

太阳的内部日冕磁场的场模型，如在非常高的纬度观测到的，解释了26天周期性的高能粒子事件。 本项目探讨了经修订的日光层磁场模型（菲斯克，1996年）的结果，包括解释慢太阳风、太阳风中的元素丰度、拾取离子的动力学和宇宙线调制。 研究人员将研究以下方面的后果：（1）高纬度经常性高能粒子事件，（2）宇宙射线在日光层中的传播，（3）太阳风的加速，以及（4）拾取离子在日光层中的传播。 同时，本研究将从多Vantage对修正后的模型进行检验。 研究人员希望通过更深入地了解日光层磁场来增加对日光层动力学的理解。
