9418803 Herbst This project is concerned with the chemistry that occurs in interstellar clouds and other cool astronomical objects. Most of the molecules are organic in nature although the most abundant molecule is simple molecular hydrogen. In addition to the gas phase molecules, astronomers are also able to detect condensed phase molecules that are located on mantles surrounding the cores of dust particles. Dr. Herbst will employ new and improved chemical models for a variety of astronomical regions ranging from interstellar clouds to circumstellar envelopes to planetary nebulae. The development of molecular complexity is one of several problems that will be investigated because of the presence of relatively large carbonaceous molecules.

[9418803 .赫布斯特]这个项目关注的是发生在星际云和其他低温天体中的化学反应。自然界中大多数分子都是有机的，尽管最丰富的分子是简单的氢分子。除了气相分子，天文学家还能够探测到位于尘埃颗粒核心周围地幔上的凝聚态分子。赫布斯特博士将采用新的和改进的化学模型来研究各种天文区域，从星际云到星周包层再到行星状星云。由于存在相对较大的碳质分子，分子复杂性的发展是将要研究的几个问题之一。
