This proposal is concerned with the interaction of the solar wind, or other flowing plasma, with non-magnetic solar system bodies such as Venus, Mars, Titan and comets. Research in this area contributes to a broader understanding of solar-planetary relations in general and of comparative magnetospheres and ionospheres. The research emphasizes two particular aspects of solar wind interactions with non-magnetic planets: (1) collisional interactions between plasmas and neutrals, and (2) evolution of plasma distribution functions in induced magnetospheres. Specifically, proposed research tasks are: (1) completing a two- dimensional, magnetohydrodynamic model of the inner coma of comet Halley, (2) developing a two-dimensional, MHD model of the ionospheres of Mars and Titan, (3) investigating cometary pickup ions using test particle methods and quasi-linear theory, and (4) studying superthermal neutral and ion populations in the inner coma of comet Halley.

这一提议涉及太阳风或其他流动等离子体与非磁性太阳系天体（如金星、火星、泰坦和彗星）的相互作用。 这一领域的研究有助于更广泛地了解太阳与行星的一般关系以及磁层和电离层的比较。 这项研究强调了太阳风与非磁性行星相互作用的两个特殊方面：（1）等离子体和中性粒子之间的碰撞相互作用，以及（2）感应磁层中等离子体分布函数的演化。 具体而言，拟议的研究任务是：（1）完成哈雷彗星内彗发的二维磁流体动力学模型，（2）开发火星和土卫六电离层的二维MHD模型，（3）使用测试粒子方法和准线性理论研究彗星拾取离子，（4）研究哈雷彗星内彗发的超热中性粒子和离子布居。
