Dr. Goodman will explore the dense core structures in molecular clouds, to better understand the interface between quiescent cores and the turbulent molecular cloud environment that contains them. This study will cover more than 200 cores located in seven separate molecular cloud complexes. It will combine information gleaned from both emission and extinction maps to create the largest sample of dust column density and temperature maps of cores that has yet been made. The newly created maps will be used to address specific open issues in star formation theory, including: i) the evolution of cores toward star formation; ii) the nature of the gravitational wells in which cores find themselves; and iii) the relation of cores to the larger molecular cloud topology.The results of this research will be made publicly available on several online interfaces, including the World Wide Telescope site and Google Sky. Dr. Goodman will participate in the development of a new science curriculum at an independent school which will incorporate these results.

古德曼博士将探索分子云中的致密核结构，以更好地理解静止核和包含它们的湍流分子云环境之间的界面。这项研究将涵盖位于7个独立分子云复合物中的200多个核心。它将结合从发射和消失图中收集的信息，创建迄今为止最大的尘埃柱密度样本和岩心温度图。新创建的地图将用于解决恒星形成理论中的特定开放问题，包括：i)核心向恒星形成的演变；Ii)岩心所在的引力井的性质；iii)核与更大分子云拓扑的关系。这项研究的结果将在几个在线界面上公开，包括世界望远镜网站和b谷歌天空。古德曼博士将参与一所独立学校的新科学课程的开发，该课程将纳入这些成果。
