High resolution interferometer and single-dish observations of young, deeply embedded stellar systems reveal a complex chemistry in the circumstellar environments of low to intermediate mass stars. Depletions of gas-phase molecules, grain mantle evaporation, and shock interactions actively drive chemical processes in different regions around young stars. We present results for two systems, IRAS 05338-0624 and NGC 1333 IRAS 4, to illustrate the behavior found and to examine the physical processes at work.

星际环境中化学过程的观测

高分辨率干涉仪和对年轻、深深嵌入恒星系统的单盘观测揭示了低质量到中等质量恒星的星周环境中的复杂化学。气相分子的消耗、颗粒地幔蒸发和激波相互作用积极推动了年轻恒星周围不同区域的化学过程。我们展示了两个系统 IRAS 05338-0624 和 NGC 1333 IRAS 4 的结果，以说明发现的行为并检查工作中的物理过程。
