CAREER: Order-of-Magnitude Problems in Star Formation and Minority Representation

ast - 0349075 - stassundr。范德比尔特大学（Vanderbilt University）的Keivan Stassun将执行一项多方面的合作研究计划，包括观测和数值研究两部分，目标是解决恒星形成中的数量级问题。在他的研究中，他将涉及：1。低质量前主序星质量的经验测定：1。年轻恒星的角动量演化：原恒星环境的解释性三维计算机模型。利用现有的范德比尔特资源，这项工作包括一个广泛的国际研究项目，将为年轻恒星提供质量和角动量的测量，以及最先进的原恒星复杂环境的计算机模拟。这些测量结果将用于模拟测试恒星形成和早期恒星演化的前沿理论。Stassun将执行一个连贯的、系统的教育和推广计划，将其整合到研究中，目标是解决天文学和天体物理学中少数民族代表性不足的数量级问题。他的工作将：1 .加强少数民族学生的科学学习。2 .增加K-12科学教师的专业发展机会，特别是在少数民族高中教学的教师；3 .培养一批少数民族本科生和硕士生攻读天文学和天体物理学博士学位；准备研究生为他们未来的角色整合研究和教育。这一雄心勃勃的计划将与附近的菲斯克大学（Fisk University）合作，这是一所历史悠久的黑人大学。

AST-0349075StassunDr. Keivan Stassun, at Vanderbilt University, will execute a multi-faceted, collaborative research plan, involving both observational and numerical research components, with the goal of addressing order-of-magnitude problems in star formation. In his research, he will address:1. Empirical determinations of masses for low-mass pre-main-sequence stars: 2. Angular momentum evolution of young stars: 3. Interpretive 3-D computer models of protostellar environments. Leveraging extant Vanderbilt resources, this work encompasses a broad, international research program that will provide measurements of masses and angular momenta for young stars, as well as state-of-the-art computer simulations of the complex environments of protostars. These measurements will then be used in simulations to test forefront theories of star formation and early stellar evolution.Dr. Stassun will execute a coherent, systemic education and outreach plan, integrated into the research, with the goal of addressing the order-of-magnitude under representation of minorities in astronomy and astrophysics. His work will: 1. Enhance science learning for minority K-12 students: 2. Increase professional development opportunities for K-12 science teachers, especially those teaching at minority high-schools: 3. Train a cadre of minority undergraduate and Masters-level students for PhD study in astronomy and astrophysics: 4. Prepare graduate students for their future roles integrating research and education. This ambitious plan will be made possible by working in partnership with nearby Fisk University, an Historically Black University.
