AST-0607641INSTITUTION: Dartmouth CollegePI: Hans MuellerTITLE: Modeling Cool Stellar Winds Interacting with a Partially Ionized Interstellar MediumABSTRACTDr. Hans Mueller, at Dartmouth College, will undertake a program to model regions carved into the local interstellar medium by the winds of cool main sequence stars in the Solar neighborhood. Comparison of these models to high-resolution Lyman-alpha absorption spectra and X-ray emission observations of gas near the cavity boundaries will then be made. The goal of the work is to add to our understanding of low-mass stellar winds, as well as the properties of the interstellar medium within a few parsecs of the Sun. The project involves a graduate student and undergraduates, including first-year undergraduate student interns in the Women-in-Science-Project at Dartmouth College. In addition, the project contains multi-disciplinary elements, with space plasma physics methods being applied to astrophysical settings.

AST-0607641机构：达特茅斯学院 PI：Hans Mueller 标题：模拟与部分电离星际介质相互作用的冷恒星风摘要博士。达特茅斯学院的汉斯·穆勒（Hans Mueller）将开展一项计划，对太阳附近的冷主序恒星的风雕刻成当地星际介质的区域进行建模。 然后将这些模型与腔边界附近气体的高分辨率莱曼-α 吸收光谱和 X 射线发射观测进行比较。这项工作的目标是加深我们对低质量恒星风以及太阳几秒差距内星际介质特性的理解。 该项目涉及一名研究生和本科生，其中包括达特茅斯学院女性科学项目的一年级本科生实习生。此外，该项目还包含多学科元素，将空间等离子体物理方法应用于天体物理环境。
