Chemical modeling of aminoketene, ethanolamine, and glycine production in interstellar ices
Sydney A. Willis, Serge A. Krasnokutski, Nathaniel J. Morin +1
Icy interstellar dust grains are a source of complex organic molecule (COM) production, although their formation mechanisms are debated. Laboratory experiments show that atomic C d…
Cyclic C as the carrier of the diffuse interstellar band at 503.9 nm?
Serge. A. Krasnokutski, Lisa Ganner, Milan Ončák +5
The diffuse interstellar bands (DIBs) have remained a mystery in astronomy since their discovery over a century ago. The only currently known carrier is C responsible for…
Ly- processing of solid-state Ethanolamine: Potential Precursors to Sugar and Peptide Derivatives
T. Suhasaria, S. M. Wee, R. Basalgète +4
Ethanolamine (EA), a key component of phospholipids, has recently been detected in the interstellar medium within molecular clouds. To understand this observation, laboratory studi…
Infrared Spectra of Solid-State Ethanolamine: Laboratory Data in Support of JWST Observations
T. Suhasaria, S. M. Wee, R. Basalgète +4
Ethanolamine (NHCHCHOH, EA) has been identified in the gas phase of the ISM within molecular clouds. Although EA has not been directly observed in the molecular ice pha…
Formation of the simplest amide in molecular clouds: formamide (NHCHO) and its derivatives in HO-rich and CO-rich interstellar ice analogs upon VUV irradiation
K. -J. Chuang, C. J\{"a}ger, S. A. Krasnokutski +2
The astronomical detection of formamide (NHCHO) toward various star-forming regions and in cometary material implies that the simplest amide might have an early origin in dark…
The C60:C60+ ratio in diffuse and translucent interstellar clouds
Gaël Rouillé, Serge A. Krasnokutski, Yvain Carpentier
Context. Insight into the conditions that drive the physics and chemistry in interstellar clouds is gained from determining the abundance and charge state of their components. Aims…
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…
Ultra-Low-Temperature Reactions of Carbon Atoms with Hydrogen Molecules
S. A. Krasnokutski, M. Kuhn, M. Renzler +3
The reactions of carbon atoms with dihydrogen have been investigated in liquid helium droplets at = 0.37 K. A calorimetric technique was applied to monitor the energy released…
Dissociative photoionization of polycyclic aromatic hydrocarbon molecules carrying an ethynyl group
Gaël Rouillé, Serge A. Krasnokutski, Daniele Fulvio +5
The life cycle of the population of interstellar polycyclic aromatic hydrocarbon (PAH) molecules depends partly on the photostability of the individual species. We have studied the…
Cold condensation of dust in the ISM
Gaël Rouillé, Cornelia Jäger, Serge A. Krasnokutski +2
The condensation of complex silicates with pyroxene and olivine composition at conditions prevailing in molecular clouds has been experimentally studied. For this purpose, molecula…
Formation of silicon oxide grains at low temperature
S. A. Krasnokutski, G. Rouille, C. Jager +3
The formation of grains in the interstellar medium, i.e., at low temperature, has been proposed as a possibility to solve the lifetime problem of cosmic dust. This process lacks a…
