Intrinsic Properties of RR Lyrae Variables

AST-9988259 LaydenDR.鲍林格林州立大学的安德鲁·莱登将领导一个研究项目，该项目包括四个不同的项目，总体目标是提高我们对银河系中古老恒星群的理解。莱登博士将对球状星团NGC3201中的天琴座RR恒星进行光度测量；他将对富含金属的球状星团中的天琴座RR恒星进行调查；他将把天琴座RR恒星观测作为测量星际变红的工具；他还将研究人马座矮星系中恒星形成的历史。该研究项目以学生参与的程度和程度来区分，这将有助于促进本科生教育和莱登博士所在机构的职前教师的经验。该奖项由天文科学部银河天文计划资助。*

AST-9988259LaydenDr. Andrew Layden of Bowling Green State University will direct a research program comprising four distinct projects that have the overall objective of improving our understanding of the old stellar populations in our Galaxy. Dr. Layden will do photometry of RR Lyrae stars in the globular cluster NGC3201; he will do a survey of RR Lyrae stars in metal-rich globular star clusters; he will use RR Lyrae star observations as a tool to measure interstellar reddening; and he will investigate the history of star formation in the Sagittarius Dwarf galaxy. The research program is distinguished by the level and extent of student involvement which will serve to promote undergraduate education and experience for pre-service teachers at Dr. Layden's institution. This award is funded out of the Galactic Astronomy Program in the Division of Astronomical Sciences.***
