Sensitivity analysis of our model to the oxygen atom diffusion energy for CO2 ice (dashed lines) and FA (suming c-t abundances). Values are represented with respect to H2O column density- The difussion Ediff energy is defined from the Ediff/Ebin parameter in our models. Ediff/Ebin is set to 0.25, 0.30 and 0.40 in those models. The pale blue zone represents the observationally constrained abundances of CO2 (Boogert et al. 2015; McClure et al. 2023) and the pale yellow zone represent the same for FA (Boogert et al. 2015; Rocha et al. 2024). We assume that FA and HCOO– abundances sum. -- astro-ph.GA

Piecing Together Formic Acid Isomerism In Dark Clouds. Detection Of Cis-formic Acid In TMC-1 And Astrochemical Modeling

by Keith CowingSeptember 25, 2025

The presence of molecular isomers in interstellar environments has become a topic of growing interest within the astrochemical community.
