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.

AST-0607567机构：印第安纳州大学PI：Constantine Deliyannis题目：较老疏散星团的锂和金属丰度 摘要Dr.印第安纳州大学的Constantine Deliyannis将研究7个主要和几个次要开放星星星团中化学锂（Li）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。 Deliyannis博士在威斯康星-印第安纳-耶鲁-NOAO（WIYN）开放集群研究中的工作解决了特定领域的问题。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事业。 Deliyannis博士有招募妇女和少数族裔的记录，预计这种情况将继续下去。 Deliyannis博士还将进行毕业和以后的面试，以评估学生培训，他将把他的研究成果纳入课堂，并在一定程度上根据研究进行各种公开演讲。
