Formation of Complex Organic Molecules in Prestellar Cores: The Role of Non-Diffusive Grain Chemistry
Katerina Borshcheva, Gleb Fedoseev, Anna F. Punanova +3
We present the results of astrochemical modeling of complex organic molecules (COMs) in the ice and gas of the prestellar core L1544 with the recently updated MONACO rate equations…

Modelling methanol and hydride formation in the JWST Ice Age era
Izaskun Jiménez-Serra, Andrés MegÃas, Joseph Salaris +19
(Abridged) JWST observations have measured the ice composition toward two highly-extinguished field stars in the Chamaeleon I cloud. The observed extinction excess on the long-wave…

Correlation between formaldehyde and methanol in prestellar cores
A. F. Punanova, K. Borshcheva, G. S. Fedoseev +3
Formaldehyde is a key precursor in the formation routes of many complex organic molecules (COMs) in space. It is also an intermediate step in CO hydrogenation sequence that leads t…
