Infrared Spectroscopic Studies in Stellar Abundances and Galactic Chemical Evolution

恒星丰度和银河系化学演化的红外光谱研究0407057巴拉钱德兰博士。马里兰大学的Suchitra Balachandran将继续进行一项计划，以确定银河中心恒星中恒星大气的化学丰度。这项工作包括测量新的不同元素，并将之前的工作扩展到较暗的恒星，以研究较老的恒星群。这项研究还将扩展到银河系的凸起。此外，PI将得出银河系和麦哲伦星云中发光的超巨星的化学丰度和同位素比率，目的是限制恒星内部混合的物理学。教育学生，包括本科生和研究生，是拟议中的研究的主要和更广泛的影响。国际和平协会将继续特别努力指导年轻女性。将开展与马里兰大学天文台开放之家有关的公众宣传活动，国际天文台将通过在与其研究专长有关的委员会中提供服务，继续为天文学社区服务。

Infrared Spectroscopic Studies in Stellar Abundances and Galactic Chemical EvolutionABSTRACTAST 0407057 BalachandranDr. Suchitra Balachandran, at the University of Maryland, will continue a program to determine chemical abundances of stellar atmospheres in stars in the Galactic Center. The work involves the measurement of new different elements, and extends the previous work to fainter stars, for the purpose of studying older stellar populations. This study will also be extended into the Bulge of the Galaxy. Additionally, the PI will derive chemical abundances and isotope ratios in luminous supergiant stars in the Milky Way and in the Magellanic Clouds, for the purpose of constraining the physics of internal mixing within stars.Educating students, both at the undergraduate and graduate level, is a major broader impact of the proposed research. The PI will continue to make a special effort to mentor young women. Public outreach activities associated with the University of Maryland Observatory Open Houses will be undertaken, and the PI will continue to serve the astronomical community through service on committees related to her research expertise.
