Cosmic Ray Modulation Using Neutron Monitors and Spacecraft Cosmic Ray Detectors in the Inner Outer Helisophere

研究人员继续研究整个日光层的宇宙射线调制，使用来自华盛顿山中子监测器和IMP，旅行者1号和2号以及先锋10号航天器的数据。 他们专注于11年和22年的变化，在1 Au和40 Au在外层日光层，检查数据，从几个能量和物种的异常和银河宇宙射线。 在异常宇宙射线数据的一个特别令人困惑的方面，这些粒子似乎在太阳磁极转换前后的两年里完全消失。 研究人员正在进一步研究这种异常成分的时间行为，因为他们认为外日光层的影响在整个太阳调制中发挥的作用比以前的理论研究表明的要大得多。 此外，他们继续分析太阳宇宙射线事件，集中研究在太阳上相互作用的质子和这些事件中的行星际质子是否来自太阳上的同一粒子群，并研究在大耀斑事件中相互作用的高能太阳质子能谱的快速时间变化。

Investigators continue studying cosmic ray modulation throughout the heliosphere, using data from the Mount Washington neutron monitor and the IMP, voyager 1 and 2, and Pioneer 10 spacecrafts. They focus on 11-year and 22-year variations at 1 AU and 40 AU in the outer heliosphere, examining data from several energies and species of both anomalous and galactic cosmic rays. In one particularly puzzling aspect of anomalous cosmic ray data, these particles appear to completely vanish for two years around the changeover of solar magnetic polarity. The investigators are further studying temporal behavior of this anomalous component, as they believe effects in the outer heliosphere play a much greater role in overall solar modulation than previous theoretical studies suggest. In addition, they continue analyzing solar cosmic ray events, concentrating on whether or not protons interacting at the Sun and interplanetary protons in these events originate from the same particle population at the Sun, and studying rapid temporal variations in the energy spectra of interacting energetic solar protons in large flare events.
