Solar Wind Interaction with Non-Magnetic Planets

这笔拨款将继续支持太阳风与金星、火星和彗星等非磁性太阳系天体相互作用的研究。这一领域的研究有助于对太阳-行星和太阳-地的关系有更广泛和比较的了解。日地物理学是研究太阳如何影响地球/行星环境的学科。在光谱的可见光和紫外线区域，太阳辐射是太阳和行星之间最明显的相互作用方式，但我们现在认识到太阳风也强烈影响地球和行星的高层大气、电离层和磁层。每个行星的物理环境都是不同的，因此每个行星环境与太阳风的相互作用也不同。共同研究这些相互作用——比较磁层的主题——非线性地增加了我们要学习的数量和我们理解的质量。这里计划的工作将把关于金星大气层的知识转移到火星上。特别是，火星的电离层将被建模。

This grant continues support for studies of the solar wind interaction with non-magnetic solar system bodies such as Venus, Mars, and comets. Research in this area contributes to a broader and comparative understanding of solar-planetary, and solar- terrestrial, relations in general. Solar-terrestrial physics is the study of how the sun affects the terrestrial/planetary environment. Solar radiation, in both the visible and ultraviolet regions of the spectrum, is the most obvious means of interaction between the sun and the planets, but we now recognize that the solar wind also strongly influences the upper atmospheres, ionospheres, and magnetospheres of the earth and planets. The physical environment of each of the planets is different and accordingly each planetary environment interacts differently with the solar wind. Studying these interactions collectively -- the subject of comparative magnetospheres -- increases nonlinearly the amount to be learned and the quality of our understanding. The work planned here will transfer the knowledge gained on the Venusian Atmosphere to that of Mars. In particular, the ionosphere of Mars will be modelled.
