The Gas-Phase Chemistry of Organic Molecules in Interstellar Clouds with Dynamical Mixing
Abstract
It is shown that, if mixing between diffuse and dense clumps with no gas intermediate in density is considered, it is necessary to mix in large amounts of neutral atomic carbon rather than the singly ionized variety to maintain high abundances of organic molecules at t much greater than 10,000 yr. On the other hand, if a more natural model in which gas condensation occurs before mixing is considered, the very act of compression is a significant source of complex molecules. In addition, high abundances of organic molecules are preserved for a large range of mixing times.
