The Acceleration and Transport of particles Energized in Solar Flares and in the Interplantary Medium

这项调查主要基于对IMP-8、ISEE-1、ISEE/3/ICE航天器上近地星际介质探测器以及旅行者号深空探测器探测器上现有高能粒子观测结果的分析。将进行的具体研究包括：1.太阳耀斑粒子加速。IMP、ISEE、Helios和Voyager航天器上的传感器已经收集了数据，这些数据将被结合在一起，在大约2.5年的能量范围内构建粒子光谱形式，以测试加速模型的光谱预测。2.行星际激波加速。来自ISEE/ICE和旅行者号航天器的高能粒子、等离子体和场数据将被用来探测粒子聚集的地点和机制，方法是：(A)研究激波加速在太阳粒子事件衰变阶段的作用，(B)在1AU和4AU处观测到的同向旋转相互作用区中的重原子核的广泛能谱，(C)寻找准平行和准垂直激波的电子加速，以及(D)检查1985年在贾科比尼-津内尔彗星附近观测到的广泛速度范围内的水族离子光谱。3.粒子输运。来自几个航天器的数据将被用来(A)研究10-20 MeV质子在距离太阳不同径向距离上的输运，(B)研究太阳耀斑事件衰变阶段~1 MeV/核子粒子的向日各向异性与行星际磁场的拓扑特征之间的关系，以及(C)使用行星际激波附近的高能粒子、场和等离子体观测来测试粒子散射的简单模型。

This investigation is based primarily on the analysis of existing energetic particle observations from detectors on IMP-8, ISEE-1, ISEE/3/ICE spacecraft in the interplanetary medium near Earth, and from detectors on the Voyager deep space probes. Specific studies to be undertaken include: 1. Solar Flare Particle Acceleration. Sensors on IMP, ISEE, Helios, and Voyager spacecraft have collected data that will be combined to construct particle spectral forms over ~2.5 decades of energy to test spectral predictions of acceleration models. 2. Interplanetary Shock Accleration. Energetic particle, plasma and field data from the ISEE/ICE and Voyager spacecraft will be used to probe the sites and mechanisms of particle accleration by (a) examining the role, if any, of shock acceleration in solar particle event decay phases, (b) constructing broad energy spectra for heavy nuclei in co- rotating interaction regions observed at both 1 and 4 AU, (c) searching for electron acceleration at both quasi- parallel and quasi-perpendicular shocks, and (d) examining water group ion spectra over a broad velocity range for the 1985 observations near comet Giacobini-Zinner. 3. Particle Transport. Data from several spacecraft will be used to (a) study the transport of 10-20 MeV protons over different radial distances from the sun, (b) investigate the relation between sunward anisotropies of ~1 MeV/nucleon particles in solar flare event decay phases with topological features of the interplanetary magnetic field, and (c) test simple models of particle scattering using energetic particle, field, and plasma observations near interplanetary shocks.
