CAREER: Detailed Chemical Abundances in Galactic Star Clusters-- Fundamental Astronomy and Education Inside and Outside Closed Boxes

提案ID: ast -0239518机构：克莱姆森大学PI: King， JeremyDr。杰里米·金将利用他在克莱姆森大学获得的职业生涯奖，对疏散星团样本中的恒星进行高精度的化学丰度测定。他将持续测定Li、C、O、Na、Mg、Al、Si、K、Ca、Ti、Cr、Fe和Ni的丰度；这些元素有不同的核合成起源、星周凝结温度和对恒星内部/大气不透明的贡献。金博士将利用这些衍生丰度的大小和变化来解决几个基本的天体物理学问题，包括标准恒星模型的有效性、星系盘中年龄与金属丰度之间的关系、恒星中年龄与色球发射之间的关系以及星团的绝对年龄。他还将研究几个运动学定义的“恒星运动群”的化学同质性，以检验它们的存在。除了他的研究之外，金博士还将通过教育和推广来促进克莱姆森大学观测天文学的发展。他将让本科生参与他的研究，并开发与天文学相关的Java小程序，其中包含自我评估和概念扩展练习。Tiger Premier astronomy Web server （TigerPAWS）的开发不仅可以满足本科生日益增长的需求，还可以为K-12教室提供教育资料。他还将为南卡罗来纳的几个不同团体提供天文学推广项目：足球比赛中的老虎tailgate天文学，老年人生活中的老虎天文学（TigerTAILS），老虎农村观测天文学资源（TigerROAR），为农村K-12学生提供特殊教育教室，以及老虎学生在不稳定教育环境中的日常生活（TigerSTRIPES），针对青少年拘留系统下的青少年。

Proposal ID: AST-0239518Institution: Clemson University PI: King, JeremyDr. Jeremy King will use his CAREER award at Clemson University to determine high precision chemical abundances for the stars in a sample of open clusters. He will consistently determine the abundances of Li, C, O, Na, Mg, Al, Si, K, Ca, Ti, Cr, Fe, and Ni; these elements have varied nucleosynthetic origins, circumstellar condensation temperatures, and contributions to interior/atmospheric stellar opacities. Dr. King will use the magnitude and variations of these derived abundances to address several fundamental astrophysical issues, including the efficacy of standard stellar models, the relationship between age and metallicity in the galactic disk, the relationship between age and chromospheric emission in stars, and the absolute ages of star clusters. He will also study the chemical homogeneity in several kinematically-defined "stellar moving groups" as a test of their existence. In addition to his research, Dr. King will enable the growth of observational astronomy at Clemson University through education and outreach. He will involve undergraduate students in his research, and develop astronomy-related Java applets containing self-assessment and conceptual extension exercises. The development of a dedicated astronomy server, Tiger Premier Astronomy Web Server (TigerPAWS), will not only meet the increased needs of the undergraduate students but also provide educational materials for K-12 classrooms. He will also deliver astronomy outreach programs to several different groups in South Carolina: TigerTailgate Astronomy at football games, Tigers Towards Astronomy In the Life of Seniors (TigerTAILS) for senior citizens, Tiger Rural Observational Astronomy Resource (TigerROAR) for rural K-12 students populating special education classrooms, and Tiger STudents Routinely In Precarious Educational Settings (TigerSTRIPES), aimed at youth under the care of the juvenile detention system.
