Exploring the chemistry induced by energetic processing of the H2-bearing, CO-rich apolar ice layer
Rafael Martin-Domenech, Pavlo Maksiutenko, Karin I. Oberg +1
Interstellar ice mantles on the surfaces of dust grains are thought to have a bi-layered structure, with a H2O-rich polar layer, covered by a CO-rich apolar layer that probably har…
Formation of NH2CHO and CH3CHO upon UV photoprocessing of interstellar ice analogs
Rafael Martin-Domenech, Karin I. Oberg, Mahesh Rajappan
Complex organic molecules (COMs) can be produced by energetic processing of interstellar ice mantles accreted on top of dust grains. Two COMs with proposed energetic ice formation…
Entrapment of CO in CO2 ice
Alexia Simon, Karin I. Oberg, Mahesh Rajappan +1
Planet atmosphere and hydrosphere compositions are fundamentally set by accretion of volatiles, and therefore by the division of volatiles between gas and solids in planet-forming…
Oxygen atom reactions with C2H6, C2H4, and C2H2 in ices
Jennifer B. Bergner, Karin I. Oberg, Mahesh Rajappan
Oxygen atom addition and insertion reactions may provide a pathway to chemical complexity in ices that are too cold for radicals to diffuse and react. We have studied the ice-phase…
Desorption Kinetics and Binding Energies of Small Hydrocarbons
Aida Behmard, Edith C. Fayolle, Dawn M. Graninger +5
Small hydrocarbons are an important organic reservoir in protostellar and protoplanetary environments. Constraints on desorption temperatures and binding energies of such hydrocarb…
Methanol formation via oxygen insertion chemistry in ice
Jennifer B. Bergner, Karin I. Oberg, Mahesh Rajappan
We present experimental constraints on the insertion of oxygen atoms into methane to form methanol in astrophysical ice analogs. In gas-phase and theoretical studies this process h…
