Clouds, Clumps, Cores & Comets - a Cosmic Chemical Connection?
arXiv:0806.3103 · doi:10.1142/9789812836229_0014
Abstract
We discuss the connection between the chemistry of dense interstellar clouds and those characteristics of cometary matter that could be remnants of it. The chemical evolution observed to occur in molecular clouds is summarized and a model for dense core collapse that can plausibly account for the isotopic fractionation of hydrogen, nitrogen, oxygen and carbon measured in primitive solar system materials is presented.
