Long & Medium-Term Research: Inertial Confinement and the Auto-collimation of Jets This award is under the Long and Medium-Term Research at Foreign Centers of Excellence Program, which enables U.S. scientists and engineers to conduct three to twelve months of research abroad at research centers of proven excellence. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad. This award will support a four-month postdoctoral research visit by Dr. Adam Frank to the University of Leiden to work with Dr. Vincent Icke. The researchers will focus on a class of problems associated with the formation of astrophysical jets. Based on a study of bipolar outflow in Planetary Nebulae, Drs. Frank and Icke believe that a single mechanism associated with a single geometry is responsible for the ubiquitous, well collimated flows. They will use sophisticated numerical hydrodynamic code to simulate the interaction of aspherical stellar outflows and the production of jets. The goal of this project is to demonstrate the efficacy of this process over a wide range of length and time scales beginning with stars and ending with galaxies. They will then go further and provide "theoretical observations" allowing detailed comparisons of the models with what is seen in the telescope. The award recommendation provides funds to cover international travel and a stipend for four months plus a dependent allowance.

长期中期研究：惯性约束和 射流自准直 该奖项是根据长期和中期研究， 外国卓越中心计划，使美国 科学家和工程师将进行三到十二个月的 在国外经过验证的卓越研究中心进行研究。 的 该计划的奖项提供了联合研究的机会， 利用独特或互补的设施、专门知识和 国外的实验条件。 该奖项将支持为期四个月的博士后研究访问， 亚当弗兰克博士到莱顿大学与博士。 文森特·艾克 研究人员将重点研究一类问题 与天体物理喷流的形成有关。 基于 行星状星云双极外流研究 我相信一个单一的机制与一个单一的几何形状相关联 负责无处不在的，良好准直的流动。 他们将 使用复杂的数值流体动力学代码来模拟 非球面恒星外流的相互作用和喷流的产生。 该项目的目标是证明这种方法的有效性。 在广泛的长度和时间范围内的过程， 恒星和星系的终结。 他们会更进一步， 提供“理论观察”，以便详细比较 把模型和望远镜里看到的东西联系起来。 该奖项的建议提供资金，以支付国际 旅费和四个月的津贴，外加受抚养人津贴。
