Exploiting JWST to Unveil Our Icy Universe

项目highlightsa。在一系列分子云中绘制主要、次要、同位素和离子星际冰种类，探测密集的灭绝区域。yo及其文档以及云边缘，以识别它们的分布作为列密度的函数。比较冰柱密度和气相发射，根据我们目前对天体化学的理解，记录气体和固态分子之间的联系，并确定冰的丰度。将冰丰度与尘埃排放图进行比较，测试冰的形成、演化和破坏与温度、尘埃、密度和当地天体物理条件的关系。

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.
