AST-0507424INSTITUTION: University of California, Santa CruzPI: Peter BodenheimerTITLE: Problems in Giant Planet Formation ABSTRACTDr. Peter Bodenheimer and Dr. Douglas Lin, at the University of California, Santa Cruz, will undertake theoretical investigations of several areas relating to the formation of giant planets. Among the issues are: 1) What mechanisms may have slowed down migration of planets inward toward their host star; 2) What possible mechanisms exist for increasing the rate of gas accretion so that significant accretion can commence at small core masses; and 3) Did Jupiter form with a larger core, which was subsequently eroded and mixed with the gaseous envelope? These remain unsolved problems in understanding the origin of giant planets. The broader impact of the proposed work focuses on the integration of research and scientific education, by means of graduate and undergraduate involvement in the project. The research will also serve to broaden participation in the sciences, by including women in the research. Additionally, the project investigators will encourage broad dissemination of the scientific results, by means of public lectures on planetary science, as well as contributions to science journals for the general public.

AST-0507424机构：加州大学圣克鲁斯分校PI：Peter Bodenheimer标题：巨行星形成中的问题摘要博士。加州大学圣克鲁斯分校的彼得·博登海默和道格拉斯·林博士将对与巨行星形成相关的几个领域进行理论研究。 其中的问题包括：1）什么机制可能减缓了行星向其主恒星向内迁移的速度； 2）存在什么可能的机制来增加气体吸积速率，以便在小的核心质量处开始显着的吸积； 3）木星是否形成了一个更大的核心，随后被侵蚀并与气体包层混合？ 在理解巨行星的起源方面，这些仍然是未解决的问题。 拟议工作的更广泛影响侧重于通过研究生和本科生参与该项目来整合研究和科学教育。 该研究还将通过让女性参与研究来扩大对科学的参与。此外，项目研究人员将通过行星科学公开讲座以及向公众投稿的方式，鼓励广泛传播科学成果。
