Interstellar carbonaceous dust erosion induced by X-ray irradiation of water ice in star-forming regions
K. -J. Chuang, C. Jaeger, N. -E. Sie +5
The chemical inventory of protoplanetary midplanes is the basis for forming planetesimals. Among them, solid-state reactions based on CO/CO toward molecular complexity on inter…
A cryogenic ice setup to simulate carbon atom reactions in interstellar ices
D. Qasim, M. J. A. Witlox, G. Fedoseev +7
The design, implementation, and performance of a customized carbon atom beam source for the purpose of investigating solid-state reaction routes in interstellar ices in molecular c…
An experimental study of the surface formation of methane in interstellar molecular clouds
D. Qasim, G. Fedoseev, K. -J. Chuang +4
Methane is one of the simplest stable molecules that is both abundant and widely distributed across space. It is thought to have partial origin from interstellar molecular clouds,…
Formation of complex molecules in translucent clouds: Acetaldehyde, vinyl alcohol, ketene, and ethanol via nonenergetic processing of C2H2 ice
K. -J. Chuang, G. Fedoseev, D. Qasim +6
Complex organic molecules (COMs) have been identified toward high- and low-mass protostars as well as molecular clouds, suggesting that these interstellar species originate from th…
Synthesis of solid-state Complex Organic Molecules through accretion of simple species at low temperatures
D. Qasim, G. Fedoseev, K. -J. Chuang +6
Complex organic molecules (COMs) have been detected in the gas-phase in cold and lightless molecular cores. Recent solid-state laboratory experiments have provided strong evidence…
Formation of interstellar propanal and 1-propanol ice: a pathway involving solid-state CO hydrogenation
D. Qasim, G. Fedoseev, K. -J. Chuang +6
1-propanol (CH3CH2CH2OH) is a three carbon-bearing representative of primary linear alcohols that may have its origin in the cold dark cores in interstellar space. To test this, we…
Extension of the HCOOH and CO2 solid-state reaction network during the CO freeze-out stage: inclusion of H2CO
D. Qasim, T. Lamberts, J. He +5
Formic acid (HCOOH) and carbon dioxide (CO2) are simple species that have been detected in the interstellar medium. The solid-state formation pathways of these species under experi…
H2 chemistry in interstellar ices: the case of CO ice hydrogenation in UV irradiated CO:H2 ice mixtures
K. -J. Chuang, G. Fedoseev, D. Qasim +3
Context. In dense clouds, hydrogenation reactions on icy dust grains are key in the formation of molecules, like formaldehyde, methanol, and complex organic molecules (COMs). These…
Solid-state production of complex organic molecules: H-atom addition versus UV irradiation
K. -J. Chuang
Complex organic molecules (COMs) have been observed in comets, hot cores and cold dense regions of the interstellar medium. It is generally accepted that these COMs form on icy dus…
Formation of Glycerol through Hydrogenation of CO ice under Prestellar Core Conditions
Gleb Fedoseev, Ko-Ju Chuang, Sergio Ioppolo +3
Observational studies reveal that complex organic molecules (COMs) can be found in various objects associated with different star formation stages. The identification of COMs in pr…
