Laboratory and Observational Studies of Refractory Molecules and Ions: Tracing the Metallic Elements from AGB Stars into the ISM

单位：亚利桑那大学api: Lucy ZiurysTITLE：难熔分子和离子的实验室和观测研究：从AGB恒星到ISM的金属元素追踪亚利桑那大学的露西·齐瑞斯将通过联合实验室和观测项目，对难熔元素的化学性质进行研究。实验室研究将集中在新的金属氰化物和碳化物种类以及一类新的含金属分子离子。将进行观测，以在星周和星际气体中寻找可能的新物种。其目标是提供了解尘埃颗粒组成、元素消耗、电离平衡和气相化学所需的信息，并了解演化恒星的质量损失、星际介质中物质的再循环、核合成和银河系化学演化。这项工作是跨学科的，将涉及研究生和本科生，以及博士后。将努力吸引女学生。此外，Ziurys博士积极参与跨学科课程的开发和基础分子光谱学网站。她还与工业界合作开发一种与国防和国土安全相关的高灵敏度气相光谱仪。

AST-0607803INSTITUTION: University of ArizonaPI: Lucy ZiurysTITLE: Laboratory and Observational Studies of Refractory Molecules and Ions: Tracing the Metallic Elements from AGB Stars into the ISM ABSTRACTDr. Lucy Ziurys, at the University of Arizona, will undertake research on the chemistry of refractory elements, by means of a joint laboratory and observational program. The laboratory investigations will focus on new metal cyanide and carbide species along with a new class of metal-bearing molecular ions. Observations will be undertaken to search for possible new species in circumstellar and interstellar gas. The goal is to provide information that is needed to understand dust grain composition, elemental depletions, ionization balance, and gas-phase chemistry, and for understanding mass loss from evolved stars, recycling of material in the interstellar medium, nucleosynthesis and Galactic chemical evolution.The work is interdisciplinary and will involve graduate and undergraduate students, along with a postdoc. Efforts will be made to engage female students. Additionally, Dr. Ziurys is actively involved in the development of interdisciplinary courses and a website for basic molecular spectroscopy. She is also collaborating with industry in developing a highly sensitive gas-phase spectrometer that has relevance to defense and homeland security.
