0318835BrownThis award supports the PI and students from the University of Colorado-Boulder in a collaboration with Kjell Erksson of the Department of Astronomy and Space Physics at the University of Uppsala. The technical focus of the project is to develop accurate models of the conditions in the extended atmospheres of evolved cool stars. The complementary expertise of the US and Swedish groups will make it possible to model the inhomogeneous wind outflow from evolved giants and super giants, model the carbon monoxides lines in dwarfs and giants, measure stellar magnetic fields using Zeeman splitting and state-of-the-art radiative transfer codes, and establish evolutionary positions and masses of late-type giants and super giants.The broader impacts of this collaboration are that it increases interactions between US researchers and those in Sweden, it promotes collaborative opportunities and career development for US students, and it enhances the infrastructure for research and education by laying the groundwork for future international research and education opportunities, especially through a planned international summer school on Analysis and Modeling of Stellar Spectra.

0318835Brownisthis奖与科罗拉多大学博尔德大学的PI和学生与乌普萨拉大学天文学与太空物理系的Kje​​ll Erksson合作。 该项目的技术重点是在不断发展的酷星的扩展大气中开发准确的条件模型。 美国和瑞典群体的互补专业知识将使从矮人和巨人中的碳一氧化碳线模型建模不均匀的空白流出，并使用Zeeman散布并进行了当前的辐射转移，并建立了众多的进化范围，并建立了巨大的庞大的庞大的庞大的胜利，并建立了恒星的磁场。这种合作是，它增加了美国研究人员与瑞典的研究人员之间的互动，它可以为我们的学生促进协作机会和职业发展，并通过为未来的国际研究和教育机会奠定基础，尤其是通过计划的国际暑期学校对StellAR Spectra的分析和建模来增强研究和教育的基础架构。
