S. B. Charnley, S. D. Rodgers (NASA Ames)
TL;DR
This paper explores the link between interstellar cloud chemistry and cometary matter, proposing a model for dense core collapse that explains isotopic fractionation in primitive solar system materials.
Contribution
It introduces a model for dense core collapse that accounts for isotopic fractionation observed in cometary and primitive solar system materials.
Findings
Chemical evolution in molecular clouds is summarized.
A plausible model for dense core collapse is presented.
Isotopic fractionation in solar system materials is explained.
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.
