Formation of nitriles and isonitriles by the heavy-ion irradiation of propionitrile in N2-rich astrophysical ices
Ana L. F. de Barros, David Dubois, Sreeja Raghunandanan +4
Context. Nitriles are key nitrogen-bearing organic molecules in dense clouds, star-forming regions, and nitrogen-rich icy environments. Understanding their stability and chemical e…
Chemical reactions in the nitrogen-acetone ice induced by cosmic ray analogs: relevance for the Solar System
A. L. F. de Barros, D. P. P. Andrade, E. F. da Silveira +3
The radiolysis of a nitrogen-acetone mixture, condensed at 11 K, by 40 MeV Ni ions is studied. These results are representative of studies concerning solar system ob…
Processing of formic acid-containing ice by heavy and energetic cosmic ray analogues
A. Bergantini, S. Pilling, H. Rothard +2
Formic acid (HCOOH) has been extensively detected in space environments, including interstellar medium (gas and grains), comets and meteorites. Such environments are often subjecte…
Radiolysis of Amino Acids by Heavy and Energetic Cosmic Ray Analogs in Simulated Space Environments: -Glycine Zwitterion Form
Williamary Portugal, Sergio Pilling, Philippe Boduch +2
In this work, we studied the stability of the glycine molecule in the crystalline zwitterion form, known as α-glycine (NHCHCOO) under action of heavy cosmic…
