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…
The spatial distribution of impact craters on Ryugu
Naoyuki Hirata, Tomokatsu Morota, Yuichiro Cho +40
Asteroid 162173 Ryugu has numerous craters. The initial measurement of impact craters on Ryugu, by Sugita et al. (2019), is based on Hayabusa2 ONC images obtained during the first…
Resurfacing processes constrained by crater distribution on Ryugu
Naofumi Takaki, Yuichiro Cho, Tomokatsu Morota +16
Understanding the geological modification processes on asteroids can provide information concerning their surface history. Images of small asteroids from spacecraft show a depletio…
High-Resolution Observations of Bright Boulders on Asteroid Ryugu: 1. Size Frequency Distribution and Morphology
Chiho Sugimoto, Eri Tatsumi, Yuichiro Cho +34
The near-Earth asteroid (162173) Ryugu displays a Cb-type average spectrum and a very low average normal albedo of 0.04. Although the majority of boulders on Ryugu have reflectance…
The Western Bulge of 162173 Ryugu Formed as a Result of a Rotationally Driven Deformation Process
Masatoshi Hirabayashi, Eri Tatsumi, Hideaki Miyamoto +26
162173 Ryugu, the target of Hayabusa2, has a round shape with an equatorial ridge, which is known as a spinning top-shape. A strong centrifugal force is a likely contributor to Ryu…
