Exploiting JWST to Unveil Our Icy Universe

项目亮点a.绘制一系列分子云上的主要、次要、同位素和离子星际冰物种的地图，探测密集的灭绝区域。YO及其文档以及云边缘，以确定它们的分布是列密度的函数。将冰柱密度与气相排放进行比较，根据我们目前对天体化学的理解，测试气体和固态分子之间的联系，并确定冰的丰度。将冰的丰度与尘埃释放图进行比较，测试冰的形成、演化和破坏随温度、尘埃、密度和当地天文条件的变化。

Project highlightsa. to map the major, minor, isotopic and ionic interstellar ice species across a range of molecular clouds, probing dense extinct regions. YOs and their docs as well as cloud edges, to identify their distribution as a function of column density.b. to compare ice column densities to gas-phase emission, to text the linkages between gas and solid-state, molecules according to our current astrochemical understanding, and establish ice abundances.c. to compare ice abundances with dust emission maps, to test the formation, evolution destruction of ices as a function of temperature, dust, density and local astrophusical conditions.
