A numerical approach using a finite element model to constrain the possible interior layout of (16) Psyche
Yaeji Kim, Masatoshi Hirabayashi
Asteroid (16) Psyche is notable for the largest M-type asteroid and has the high radar albedo among the main-belt asteroids. The object is likely a mixture of metal and silicates b…
The Excited Spin State of Dimorphos Resulting from the DART Impact
Harrison F. Agrusa, Ioannis Gkolias, Kleomenis Tsiganis +12
The NASA Double Asteroid Redirection Test (DART) mission is a planetary defense-driven test of a kinetic impactor on Dimorphos, the satellite of the binary asteroid 65803 Didymos.…
Hayabusa2 Extended Mission: New Voyage to Rendezvous with a Small Asteroid Rotating with a Short Period
M. Hirabayashi, Y. Mimasu, N. Sakatani +41
Hayabusa2 is the Japanese Asteroid Return Mission and targeted the carbonaceous asteroid Ryugu, conducted by the Japan Aerospace Exploration Agency (JAXA). The goal of this mission…
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…
