The surface sensitivity of rubble-pile asteroids during a distant planetary encounter: Influence of asteroid shape elongation
Yaeji Kim, Masatoshi Hirabayashi, Richard P Binzel +3
We numerically investigate how an asteroid's elongation controls the sensitivity of its surface to tidal effects during a distant planetary encounter beyond the Roche limit. We ana…
Spin-driven evolution of asteroids' top-shapes at fast and slow spins seen from (101955) Bennu and (162173) Ryugu
Masatoshi Hirabayashi, Ryota Nakano, Eri Tatsumi +14
Proximity observations by OSIRIS-REx and Hayabusa2 provided clues on the shape evolution processes of the target asteroids, (101955) Bennu and (162173) Ryugu. Their oblate shapes w…
Mass shedding activities of Asteroid (3200) Phaethon enhanced by its rotation
Ryota Nakano, Masatoshi Hirabayashi
Asteroid (3200) Phaethon, a B-type asteroid, has been active during its perihelion passages. This asteroid is considered to be a source of the Geminid meteor stream. It is reported…
