Star formation occurs within the densest gas of molecular clouds and planets form out of even denser gas surrounding protostars. In this proposal, I describe plans to exploit the newest observational technologies to determine the origins of substructure in molecular clouds that promote the formation of stars and planets, i.e., filaments, clumps, and disks.  With these projects, Canada will continue its leading role in probing the origins of stars and planets.  These projects will also be undertaken primarily by students under my direct supervision.

星星的形成发生在分子云的致密气体中，而行星则是由原恒星周围更致密的气体形成的。在这个建议中，我描述了利用最新的观测技术来确定分子云中促进恒星和行星形成的子结构起源的计划，即，细丝、团块和盘。通过这些项目，加拿大将继续在探索恒星和行星的起源方面发挥主导作用。这些项目也将主要由我直接指导的学生承担。
