Modeling cool stellar winds interacting with a partially ionized ISM

介绍：达特茅斯学院PI：Hans MuellerTITLE：模拟冷恒星风与部分电离星际介质的相互作用。达特茅斯学院的汉斯·米勒将开展一个项目，模拟太阳附近被冷的主序恒星的风雕刻成当地星际介质的区域。然后将这些模型与空穴边界附近气体的高分辨率Lyman-Alpha吸收光谱和X射线发射观测进行比较。这项工作的目标是增加我们对低质量恒星风的理解，以及在离太阳几秒的范围内星际介质的性质。该项目涉及一名研究生和本科生，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，该项目包含多学科内容，将空间等离子体物理方法应用于天体物理环境。

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.
