Tram, L. N., et al. (2026)
“One-dimensional and time-dependent modelling of complex organic molecules in protostars”
Accepted for A&A
arXiv:2601.00731

Note

This work implements one-dimensional, time-dependent modelling for protostars in UCLCHEM. These improvements are scheduled for release with UCLCHEM 4.0 and are not yet available in the main branch.
