Abstract: ATM 9908848Proposal Title: Self-Consistent Solar Wind Acceleration and Heating Due to Wave-Particle InteractionsPrincipal Investigator: Tom T Chang, MIT The investigators will construct the first self-consistent kinetic model of how ion and electron velocity distributions interact with plasma fluctuations in the solar wind. The main effort is to extend a successful research project on the "polar wind" emanating from the magnetosphere of the Earth to the solar wind. One of the main goals of the investigation is to provide a physical interpretation that relates observations of the solar corona to spacecraft measurements in the solar wind. Preliminary results indicate those wave particle interactions due to electromagnetic waves at ion cyclotron frequencies may provide the heating and acceleration of the solar wind in general, and the preferential acceleration of helium ions in particular.

摘要：ATM 9908848 提案标题：波粒相互作用导致的自洽太阳风加速和加热首席研究员：Tom T Chang，麻省理工学院研究人员将构建第一个自洽动力学模型，说明离子和电子速度分布如何与等离子体波动相互作用。太阳风。主要努力是将地球磁层发出的“极地风”的成功研究项目扩展到太阳风。该研究的主要目标之一是提供一种物理解释，将日冕的观测与太阳风中的航天器测量联系起来。初步结果表明，离子回旋加速器频率下的电磁波引起的波粒相互作用通常可以提供太阳风的加热和加速，特别是氦离子的优先加速。
