项目摘要
AST 0307340PI: John LairdINSTITUTION: Bowling Green State UniversityDr. John Laird, in collaboration with Bruce Carney of UNC, Chapel Hill, will carry out a suite of projects that are aimed at developing a better understanding of the stellar populations in our galaxy. They will pursue research activities in four broad areas: 1) following up on their recent observations that suggest that the surprisingly high fraction of field red horizontal branch and red giant branch stars that rotate may be linked to planet accretion, 2) the exploration of the mass-luminosity relationship for binary stars to constrain the stellar helium abundance, 3) a study of metal-poor subgiant stars to refine metallicities and determine ages, and 4) a study of local G dwarfs to investigate the chemical and dynamical evolution of the thin and thick disk populations in the solar neighborhood, and their full metallicity distribution functions, from which follow-up studies will provide details on the element-to-iron ratios as a function of [Fe/H].Undergraduate and graduate students will be involved in the research. The research activities and results will be integrated into K-16 science education through a masters program for in-service physical science teachers that emphasizes modeling research-based teaching strategies, and explicitly includes an astronomy component and a collaboration in northwest Ohio of 7-12 educators, colleges, and community and business partners to enhance recruiting, preparation, and support of 7-12 math and science teachers. ***
AST 0307340PI:约翰·莱尔德机构:鲍林格林州立大学博士。约翰·莱尔德将与北卡罗来纳大学教堂山分校的布鲁斯·卡尼合作开展一系列项目,旨在更好地了解我们银河系的恒星种群。 他们将在四个广泛领域开展研究活动:1)跟进他们最近的观察结果,这些观察结果表明旋转的场红色水平分支和红巨星分支恒星的比例高得惊人,可能与行星吸积有关;2)探索双星的质量-光度关系以限制恒星氦丰度;3)对贫金属次巨星进行研究,以细化金属丰度并确定年龄;4)一项研究 当地G矮星的研究,以研究太阳附近薄盘和厚盘族的化学和动力学演化,以及它们的全金属丰度分布函数,后续研究将提供元素铁比随[Fe/H]变化的详细信息。本科生和研究生将参与这项研究。 研究活动和结果将通过在职物理科学教师的硕士课程纳入 K-16 科学教育,该课程强调基于研究的教学策略建模,并明确包括天文学部分以及俄亥俄州西北部 7-12 名教育工作者、大学、社区和商业伙伴的合作,以加强 7-12 名数学和科学教师的招聘、准备和支持。 ***
