Using astrochemical models to simulate reactivity experiments on cold surfaces
Valeriia Sokolova, Basile Husquinet, Stephan Diana +7
The development of molecular complexity during stellar and planetary formation owes much to the interaction of gas and dust. When the first astrochemical models including solid-sta…
Deuterium fractionation and CO depletion in Barnard 5
Igor Petrashkevich, Anna Punanova, Paola Caselli +3
Deuterium fractionation provides a key diagnostic of the physical and chemical evolution of prestellar and protostellar cores, where it is strongly linked to CO depletion in cold,…
The complex organic molecular content in the L1517B starless core
Andrés MegÃas, Izaskun Jiménez-Serra, Jesús MartÃn-Pintado +5
Recent observations of the pre-stellar core L1544 and the younger starless core L1498 have revealed that complex organic molecules (COMs) are enhanced in the gas phase toward their…
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…
