AST 0307926NesvornyDr. David Nesvorny, Southwest Research Institute, will lead a study of the binary objects recently discovered in the Kuiper Belt and of the moons of the jovian planets. These two components of the present Solar System inventory probably date back to the earliest epochs. Dr. Nesvorny will study various scenarios for their formation, not solely to explain why they are there, but also to provide crucial constraints on the current models of planet formation. His research team will model three recently suggested scenarios of the formation of binary Kuiper Belt Objects to probe physical conditions that existed in the trans-Neptunian disk during early epochs. To derive constraints on jovian planet and satellite formation, the group will study the effects of collisions and gravitational perturbations on the moons in several planetary formation scenarios. Finally, they will investigate the possibility that some irregular moons formed when small objects in the inner proto-satellite disk were scattered outward by the major satellites and decoupled from them by the effect of passing planetesimals or by solar tides. To broaden the impact of this research, Dr. Nesvorny will partner with the Denver Museum of Nature and Science to bring aspects of this project's results to the Museum's visitors.***

AST 0307926NesvornyDr.西南研究所的大卫内斯沃尼将领导一项研究，研究最近在柯伊伯带发现的双星和木星行星的卫星。 目前太阳系的这两个组成部分可能可以追溯到最早的时代。 Nesvorny博士将研究它们形成的各种情况，不仅要解释它们为什么会在那里，还要为目前的行星形成模型提供关键的限制。 他的研究小组将对最近提出的三种柯伊伯带天体形成的情景进行建模，以探测早期存在于海王星外盘中的物理条件。 为了推导出木星行星和卫星形成的限制条件，该小组将研究在几种行星形成情景中碰撞和引力摄动对卫星的影响。 最后，他们将研究一些不规则卫星形成的可能性，当内部原卫星盘中的小物体被主要卫星向外散射，并通过星子或太阳潮汐的影响与它们分离时。为了扩大这项研究的影响，Nesvorny博士将与丹佛自然与科学博物馆合作，将该项目的成果带给博物馆的游客。
