Lithium and Metallicities of Older Open Clusters

AST-0607567研究：印第安纳大学PI：Constantine DeliyannisTITLE：较老疏散星团的锂和金属。印第安纳大学的康斯坦丁·德利扬尼斯将研究7个初级疏散星团和几个次级疏散星团中锂(Li)化学物质的丰度，以解决恒星结构和演化中的关键问题，这些问题最终可能对轻元素化学演化、球状星团年龄、大爆炸核合成、暗物质和宇宙学产生重大影响。具体的研究领域解决了Deliyannis博士与威斯康星-印第安纳-耶鲁-NOAO(WIYN)开放集群研究的合作问题。两名研究生和至少六名本科生将接受培训并鼓励他们从事科学职业。Deliyannis博士有招募女性和少数族裔的记录，预计这种情况将继续下去。德利扬尼斯博士还将进行毕业面试和随后的评估学生培训的访谈，他将把自己的研究成果融入课堂，并在一定程度上基于这项研究发表各种公开演讲。

AST-0607567INSTITUTION: Indiana UniversityPI: Constantine DeliyannisTITLE: Lithium and Metallicities of Older Open Clusters ABSTRACTDr. Constantine Deliyannis, at Indiana University, will study the abundance of the chemical Lithium (Li) in 7 primary and several secondary open star clusters, to address key issues in stellar structure and evolution that might ultimately have significant implications for light element chemical evolution, globular cluster ages, big bang nucleosynthesis, dark matter and cosmology. Specific areas of research address issues that follow from Dr. Deliyannis' work with the Wisconsin-Indiana-Yale-NOAO (WIYN) Open Cluster Study.Two graduate students and at least six undergraduates will be trained and encouraged to pursue careers in science. Dr. Deliyannis has a record of recruiting women and minorities, and this is expected to continue. Dr. Deliyannis will also conduct exit and later interviews for assessment of student training, and he will incorporate his research results in classrooms, and give various public talks based, in part, on the research.
