A New "Non-energetic" Route to Complex Organic Molecules in Astrophysical Environments: The C + HO HCO Solid-state Reaction
Alexey Potapov, Serge Krasnokutski, Cornelia Jäger +1
The solid-state reaction C + HO HCO was studied experimentally following the codeposition of C atoms and HO molecules at low temperatures. In spite of the…
Formation of complex organic molecules in molecular clouds: acetaldehyde, vinyl alcohol, ketene, and ethanol via the "energetic" processing of CH ice
K. -J. Chuang, G. Fedoseev, C. Scirè +5
The simultaneous detection of organic molecules of the form CHO, such as ketene (CHCO), acetaldehyde (CHCHO), and ethanol (CHCHOH), toward early st…
Ice coverage of dust grains in cold astrophysical environments
Alexey Potapov, Cornelia Jäger, Thomas Henning
Surface processes on cosmic solids in cold astrophysical environments lead to gas phase depletion and molecular complexity. Most astrophysical models assume that the molecular ice…
Sensitivity of gas-grain chemical models to surface reaction barriers: Effect from a key carbon-insertion reaction, C + H CH
Matjaž Simončič, Dmitry Semenov, Serge Krasnokutski +2
The feasibility of contemporary gas-grain astrochemical models depends on the availability of accurate kinetics data, in particular, for surface processes. We study the sensitivity…
Separate silicate and carbonaceous solids formed from mixed atomic and molecular species diffusing in neon ice
Gaël Rouillé, Cornelia Jäger, Thomas Henning
The formation and growth of refractory matter on pre-existing interstellar dust grain surfaces was studied experimentally by annealing neon-ice matrices in which potential precurso…
Constraining the detectability of water ice in debris disks
Minjae Kim, Sebastian Wolf, Alexey Potapov +2
Water ice is important for the evolution and preservation of life. Identifying the distribution of water ice in debris disks is therefore of great interest in the field of astrobio…
