Formation of hydroxylamine on dust grains via ammonia oxidation

open access: yes, 2015
The quest to detect prebiotic molecules in space, notably amino acids, requires an understanding of the chemistry involving nitrogen atoms. Hydroxylamine (NH$_2$OH) is considered a precursor to the amino acid glycine.
