Delivery of Dust Particles from Protoplanetary Disks onto Circumplanetary Disks of Giant Planets
Natsuho Maeda, Keiji Ohtsuki, Ryo Suetsugu +3
Principal regular satellites of gas giants are thought to be formed by the accumulation of solid materials in circumplanetary disks (CPDs). While there has been significant progres…
Delivery of gas onto the circumplanetary disk of giant planets: Planetary-mass dependence of the source region of accreting gas and mass accretion rate
Natsuho Maeda, Keiji Ohtsuki, Takayuki Tanigawa +2
Gas accretion onto the circumplanetary disks and the source region of accreting gas are important to reveal dust accretion that leads to satellite formation around giant planets. W…
A global system of furrows on Ganymede indicative of their creation in a single impact event
Naoyuki Hirata, Ryo Suetsugu, Keiji Ohtsuki
Furrows are a concentric system of tectonic troughs, and are the oldest recognizable surface feature on Ganymede. We analyzed the distribution of furrows utilizing Voyager and Gali…
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…
Crater-ray formation through mutual collisions of hypervelocity-impact induced ejecta particles
Toshihiko Kadono, Ayako I. Suzuki, Rintaro Matsumura +4
We investigate the patterns observed in ejecta curtain induced by hypervelocity impact (2-6 km/s) with a variety of the size and shape of target particles. We characterize the patt…
Pattern of Impact-Induced Ejecta from Granular Targets with Large Inclusions
Toshihiko Kadono, Ryo Suetsugu, Dai Arakawa +4
We performed impact experiments to observe patterns in an ejecta curtain with targets consisting of small sand particles and large inclusions comparable to or smaller than the size…
Collisional Disruption of Planetesimals in the Gravity Regime with iSALE Code: Comparison with SPH code for Purely Hydrodynamic Bodies
Ryo Suetsugu, Hidekazu Tanaka, Hiroshi Kobayashi +1
In most of the previous studies related to collisional disruption of planetesimals in the gravity regime, Smoothed Particle Hydrodynamics (SPH) simulations have been used. On the o…
Distribution of captured planetesimals in circumplanetary gas disks and implications for accretion of regular satellites
Ryo Suetsugu, Keiji Ohtsuki
Regular satellites of giant planets are formed by accretion of solid bodies in circumplanetary disks. Planetesimals that are moving on heliocentric orbits and are sufficiently larg…
Capture of planetesimals by waning circumplanetary gas disks
Ryo Suetsugu, Keiji Ohtsuki
When gas giant protoplanets grow sufficiently massive, circumplanetary disks would form. While solid bodies captured by the circumplanetary disks likely contribute to the growth of…
Orbital characteristics of planetesimals captured by circumplanetary gas disks
Ryo Suetsugu, Keiji Ohtsuki, Tetsuya Fujita
Sufficiently massive growing giant planets have circumplanetary disks, and the capture of solid bodies by the disks would likely influence the growth of the planets and formation o…
