2-aminooxazole in Astrophysical Environments: IR Spectra and Destruction Cross Sections for Energetic Processing

2-aminooxazole (2AO), a N-heterocyclic molecule, has been proposed as an intermediate in prebiotic syntheses. It demonstrated that it can be synthesized from small molecules such cyanamide and glycoaldehyde, which are present interstellar space. The aim of this work is to provide infrared spectra, the solid phase for conditions typical astrophysical environments estimate its stability toward UV photons cosmic rays. Infrared (4000-600 cm$^{-1}$) absorption spectra at 20 K, 180 300 IR band strengths, room temperature (120-250 nm) given first time species. Destruction cross-sections 9.5 10$^{-18}$ cm$^2$ 2 10$^{-16}$ were found irradiation K pure 2AO 2AO:H$_2$O ices with (6.3-10.9 eV) or 5 keV electrons, respectively. These data used half-life times molecule different environments. estimated could survive radiation rays ice mantles dense clouds beyond cloud collapse. In contrast, would very unstable surface cold Solar System bodies like Kuiper belt objects, but still within dust grain agglomerates cometesimals.
