项目摘要

AST-0302146Barranco, JosephDr. Barranco is awarded an NSF Astronomy and Astrophysics Postdoctoral Fellowship to carry out a program of research and education at the Kavli Institute for Theoretical Physics at the University of California, Santa Barbara, and then at the Harvard-Smithsonian Center for Astrophysics. He will pursue an integrated theoretical, computational, observational, and experimental program to study the dynamics of protoplanetary disks and the process of planet formation within them. High-resolution radio (millimeter and submillimeter) observations of dust emission can be used to construct detailed maps of non-axisymmetric features such as vortices, clumps, ring arcs and warps. Dr. Barranco will use three-dimensional, two-fluid simulations to model the gas and dust dynamics of the observed non-axisymmetric phenomena. The goal is to determine whether coherent structures in the gas flow can generate coherent structures in the particle concentration, and to elucidate what role this plays in the formation of the first generation of planetesimals. In addition to his research, Dr. Barranco will collaborate with the Algebra Project, a national mathematics literacy program. The Algebra Project focuses on helping low-income students and students of color (particularly African-American and Latino students) master algebra in middle school/junior high school, far earlier than the expectations of most urban/rural school districts. He will develop an algebra-based physics and astronomy curriculum that complements the goals of their program, namely math literacy, yet at the same time develops interest, intuition, appreciation, and perhaps passion, for the physical sciences. ***
AST-0302146约瑟夫·巴兰科博士。巴兰科获得了美国国家科学基金会天文学和天体物理学博士后奖学金,在加州大学圣塔芭芭拉分校卡维利理论物理研究所和哈佛-史密森天体物理学中心开展研究和教育项目。 他将追求一个综合的理论、计算、观测和实验项目来研究原行星盘的动力学以及其中行星形成的过程。灰尘排放的高分辨率无线电(毫米和亚毫米)观测可用于构建非轴对称特征的详细地图,例如涡流、团块、环弧和扭曲。 Dr. Barranco will use three-dimensional, two-fluid simulations to model the gas and dust dynamics of the observed non-axisymmetric phenomena.目标是确定气流中的相干结构是否可以在粒子浓度中产生相干结构,并阐明这在第一代星子的形成中发挥什么作用。 In addition to his research, Dr. Barranco will collaborate with the Algebra Project, a national mathematics literacy program.代数项目专注于帮助低收入学生和有色人种学生(特别是非裔和拉丁裔学生)在初中/初中掌握代数,远远早于大多数城市/农村学区的期望。他将开发基于代数的物理和天文学课程,以补充他们的计划目标,即数学素养,同时培养对物理科学的兴趣、直觉、欣赏,也许还有热情。 ***
