CO2 infrared spectra on silicate dust grain analogs: Implications for JWST observations

Tushar Suhasaria, Vanessa Leuschner, Cornelia Jaeger +2

Carbon dioxide is one of the three most abundant species within the ice mantles around dust grains inside molecular clouds. Since a substantial amount of interstellar grains is mad…

Formation of extraterrestrial peptides and their derivatives

Serge A. Krasnokutski, Cornelia Jager, Thomas Henning +3

The formation of protein precursors, due to the condensation of atomic carbon under the low-temperature conditions of the molecular phases of the interstellar medium, opens alterna…

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…

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…

Evidence of surface catalytic effect on cosmic dust grain analogues: the ammonia and carbon dioxide surface reaction

Alexey Potapov, Patrice Theulé, Cornelia Jäger +1

Surface chemistry on cosmic dust grains plays an important role in the formation of molecules at low temperatures in the interstellar and circumstellar environments. For the first…

Photodesorption of water ice from dust grains and thermal desorption of cometary ices studied by the INSIDE experiment

Alexey Potapov, Cornelia Jäger, Thomas Henning

A new experimental set-up INterStellar Ice-Dust Experiment (INSIDE), was designed for studying cosmic grain analogues represented by ice-coated carbon- and silicate-based dust grai…
