Equilibrium Simplified Chemistries for H2O and CO in three-phase astrochemical models
Jonathan Rawlings, Eric Keto, Paola Caselli
Astrochemical models can be greatly simplified, with obvious computational advantages, if the reaction networks for key species can be reduced to a bare minimum. In addition, if ch…

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…

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…
