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…

Anisotropic Ejection from Active Asteroid P/2010 A2: An Implication of Impact Shattering on an Asteroid

Yoonyoung Kim, Masateru Ishiguro, Tatsuhiro Michikami +1

We revisited a mass ejection phenomenon that occurred in asteroid P/2010 A2 in terms of the dynamical properties of the dust particles and large fragments. We constructed a model a…
