Near-infrared spectral variation in Ryugu particles and implication for rapid space weathering by solar UV radiation

Abstract The 2.7 µm absorption band, represented by OH groups, in the near-infrared reflectance spectra of primitive Solar System bodies could be an indicator of the cause and degree of space weathering. We compared the absorption bands of particles sampled from the surface (chamber A) and the excav...
