Interstellar H₃O⁺

Abstract

The H₃O⁺ ion is a key species in the oxygen chemistry leading to H₂O, OH and O₂. Chemical models predict O₂ and H₂O to be the dominant oxygen-bearing molecules in interstellar clouds. However, neither of them can easily be observed in the bulk of the interstellar medium because of blockage from the Earth's atmosphere. Determination of the abundance and distribution of the precursor H₃O⁺ ion might thus provide an important indirect measure of their abundances.
