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…
Physics and Chemistry on the Surface of Cosmic Dust Grains: A Laboratory View
Alexey Potapov, Martin McCoustra
Dust grains play a central role in the physics and chemistry of cosmic environments. They influence the optical and thermal properties of the medium due to their interaction with s…
Dust/ice mixing in cold regions and solid-state water in the diffuse interstellar medium
Alexey Potapov, Jeroen Bouwman, Cornelia Jäger +1
Whether ice in cold cosmic environments is physically separated from the silicate dust or mixed with individual silicate moieties is not known. However, different grain models give…
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…
Thermal formation of ammonium carbamate on the surface of laboratory analogues of carbonaceous grains in protostellar envelopes and planet-forming disks
Alexey Potapov, Cornelia Jäger, Thomas Henning
The catalytic role of dust grain surfaces in the thermal reaction CO2 + 2NH3 NH4+NH2COO was recently demonstrated by our group. The rate coefficients for the reaction…
High-resolution gas phase spectroscopy of molecules desorbed from an ice surface: a proof-of-principle study
Patrice Theulé, Christian Endres, Marius Hermanns +2
High-resolution gas phase spectroscopy techniques in the microwave, millimeter-wave and terahertz spectral ranges can be used to study complex organic molecules desorbed from inter…
