拟议研究的主要目的是 确定对粒子加速的要求, 特别是太阳耀斑期间的电子,这是迄今为止 未解决的问题 本文将从理论上研究 加速粒子与周围等离子体的相互作用 包括与粒子、波和大尺度的相互作用, 磁场 与观察到的脉冲相位比较 辐射,如X射线、伽马射线、微波和III型 辐射用于约束模型, 加速的特性的测定 粒子将新旧两种材料进行比较 观测,因为他们成为在下一个太阳能 最大限度地,以获得更逼真的模型, 加速过程的进一步研究。 结果 从这项研究应该有直接的应用到其他领域 包括日地关系在内的科学研究, 磁层物理学、恒星耀斑、伽马射线爆发和 星系核的活动。
英文摘要
The primary purpose of the proposed research is the determination of the requirement for acceleration of particles, especially electrons during solar flares, which is as yet an unsolved problem. Theoretical studies will be made of the interaction of accelerated particles with ambient plasma including interactions with particles, waves, and large scale magnetic fields. Comparison with observed impulsive phase radiation such as X-rays, gamma rays, microwaves and type III radiation is used for constraining the models and for determination of the characteristics of the accelerated particles. Comparison will be made with both old and new observations as they become available during the next solar maximum, with the goal of obtaining more realistic models and furthering investigation of the acceleration process. Results from this research should have direct application to other areas of scientific research including solar terrestrial relations, magnetospheric physics, stellar flares, gamma ray bursts and activity in galactic nuclei.
