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

AST-0607803研究：亚利桑那大学：Lucy ZiurysTITLE：耐火分子和离子的实验室和观测研究：从AGB星追踪金属元素到ISM ABSTRACTDR。亚利桑那大学的Lucy Ziurys将通过一个联合实验室和观测计划，从事难熔元素的化学研究。实验室研究将集中在新的金属氰化物和碳化物物种以及一类新的含金属分子离子上。将进行观测，以寻找星际和星际气体中可能存在的新物种。目标是提供所需的信息，以了解尘埃颗粒组成、元素贫化、电离平衡和气相化学，以及了解演化恒星的质量损失、星际介质中物质的循环、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博士还积极参与跨学科课程和基础分子光谱学网站的开发。她还与工业界合作开发了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.
