Comparison of optical spectra between asteroids Ryugu and Bennu: II. High-precision analysis for space weathering trends

K. Yumoto, E. Tatsumi, T. Kouyama +25

The influence of space weathering on the observed spectra of C-complex asteroids remains uncertain. This has long hindered our understanding of their composition through telescope…

Comparison of optical spectra between asteroids Ryugu and Bennu:I. Cross calibration between Hayabusa2/ONC-T and OSIRIS-REx/MapCam

K. Yumoto, E. Tatsumi, T. Kouyama +25

Asteroids (162173) Ryugu and (101955) Bennu observed by Hayabusa2 and OSIRIS-REx share many properties, but spectral observations by the telescopic Optical Navigation Camera (ONC-T…
