Possible Routes for The Synthesis of Aromatic Compounds in Molecular Clouds

Year: 2025

Type: conference-paper

Abstract: We consider the synthesis of aromatic molecules in the interstellar medium under various physical conditions. It is shown that for the “standard” C/O abundance ratio 0.41 the observed abundance of complex aromatic molecules (in particular, cyanonaphthalene) is reproduced only with an unrealistic combination of physical parameters. The C/O ratio of about 1.1, suggested for TMC-1, increases the model abundances of aromatic molecules. For some combinations of physical parameters the solid phase benzene abundance relative to water ice can reach 1 %, which may possibly be detected with observations on JWST.
