AST-0607773INSTITUTION: Vanderbilt UniversityPI: Keivan StassunTITLE: A Fundamental Calibration of Pre-Main-Sequence Evolution Models for Low-Mass Stars and Brown DwarfsABSTRACTDr. Keivan Stassun (Vanderbilt University), along with Gregory W Doppmann (Gemini Observatory) and Subhanjoy Mohanty (Harvard-Smithsonian Center for Astrophysics) will undertake a program of observational research that has as its goal the fundamental calibration of theoretical evolution models for young, low-mass stars and brown dwarfs. Specifically Dr. Stassun will: 1) make accurate measurements of physical properties for pre-main-sequence (PMS) stars and brown dwarfs; and 2) test stellar interiors models and calibrate age determinations for low-mass PMS stars and brown dwarfs.Dr. Stassun will continue and expand, in collaboration with Fisk University (a Historically Black College/University located 1.5 miles from Vanderbilt), a systemic program of education, outreach, and mentoring at the K-12, undergraduate, graduate, and postdoctoral levels aimed at significantly enhancing and broadening the participation of underrepresented minorities in astronomy. The research program will be undertaken, in part, by a Vanderbilt PhD student with active participation of a Fisk-Vanderbilt Masters-to-PhD Bridge program graduate student and one or more Fisk Astronomy and Space Science Training program undergraduates.

AST-0607773机构：范德比尔特大学PI：Keivan Stassun标题：低质量恒星和褐矮星主序前演化模型的基本校准。Keivan Stassun（范德比尔特大学）、沿着Gregory W Doppmann（双子座天文台）和Subhanjoy Mohanty（哈佛-史密森天体物理中心）将开展一项观测研究计划，其目标是对年轻、低质量恒星和褐矮星的理论演化模型进行基本校准。 具体而言，Stassun博士将：1）精确测量主序前恒星和棕矮星的物理性质; 2）测试恒星内部模型，校准低质量PMS恒星和褐矮星的年龄测定。Stassun博士将与菲斯克大学合作，继续并扩大（一所历史上的黑人学院/大学，距离范德比尔特1.5英里），一个系统的教育、推广和指导计划，在K-12，本科，研究生和博士后水平的研究，旨在大大加强和扩大代表性不足的少数群体在天文学领域的参与。该研究计划将进行，部分，由一个范德比尔特博士生与菲斯克-范德比尔特硕士到博士桥梁计划研究生和一个或多个菲斯克天文学和空间科学培训计划本科生的积极参与。
