蒸发冰中的化学：未探索的领域
Chemistry in Evaporating Ices: Unexplored Territory
摘要：
我们认为，三体化学可能发生在温暖的高密度气体蒸发的瞬时co \textendash解吸事件星际冰。使用一个高度理想化的计算模型，我们探讨了从简单的物种的冰的化学转化为更复杂的物种包含几个重原子，作为密度的函数和通过的三个机构率系数。我们预测，有一个广泛的密度和速率系数，其中一个显着的化学转化可能发生。我们讨论了这一想法的热内核的天体化学的影响。
英文摘要：
We suggest that three-body chemistry may occur in warm high density gas evaporating in transient co\textendash desorption events on interstellar ices. Using a highly idealised computational model we explore the chemical conversion from simple species of the ice to more complex species containing several heavy atoms, as a function of density and of adopted three body rate coefficients. We predict that there is a wide range of densities and rate coefficients in which a significant chemical conversion may occur. We discuss the implications of this idea for the astrochemistry of hot cores.
