Profile

About
Specializing in planetary formation theory and planetary exploration, I am actively involved in the development of the next generation of planetary exploration missions from within JAXA. I am involved in the exploration programs of ESA, NASA, and JAXA, and I spend 3-4 months/year at the University of Paris.

Research Interests
Using computer simulations and theoretical methods, I aim to understand the formation and evolutionary processes of various planetary systems, small bodies, and rings (planet formation theory). I also aim to actively maximize the value of planetary exploration missions from a scientific perspective (planetary exploration science).
 
Mission Involvements
NASA Cassini / JAXA Hayabusa2 / ESA BepiColombo / JAXA MMX / JAXA Next Generation Sample-Return Mission / JAXA OPENS (Japan's first exploration of the outer solar system !?)

Searching for life on Mars and its moons
Ryuki Hyodo   Tomohiro Usui   
SCIENCE   373(6556) 742-742   Aug 2021   [Refereed]
 
Planetesimal formation around the snow line. II. Dust or pebbles?
Ryuki Hyodo   Tristan Guillot   Shigeru Ida   Satoshi Okuzumi   Andrew N. Youdin   
ASTRONOMY & ASTROPHYSICS   646    Dec 2020   [Refereed]
Around the snow line, icy pebbles and silicate dust may locally pile-up and
form icy and rocky planetesimals via streaming instability and/or gravitational
instability. We perform 1D diffusion-advection simulations that include the
back-reaction t...
 
Transport of impact ejecta from Mars to its moons as a means to reveal Martian history
Ryuki Hyodo   Kosuke Kurosawa   Hidenori Genda   Tomohiro Usui   Kazuhisa Fujita   
Scientific Reports   9(1)    Dec 2019   [Refereed]
Throughout the history of the solar system, Mars has experienced continuous asteroidal impacts. These impacts have produced impact-generated Mars ejecta, and a fraction of this debris is delivered to Earth as Martian meteorites. Another fraction o...
 
On the Impact Origin of Phobos and Deimos. I. Thermodynamic and Physical Aspects
Ryuki Hyodo   Hidenori Genda   Sébastien Charnoz   Pascal Rosenblatt   
Astrophysical Journal   845(2) 125-125   Aug 2017   [Refereed]
Phobos and Deimos are the two small moons of Mars. Recent works have shown that they can accrete within an impact-generated disk. However, the detailed structure and initial thermodynamic properties of the disk are poorly understood. In this paper...
 
Saturn's F ring and shepherd satellites a natural outcome of satellite system formation
Ryuki Hyodo   Keiji Ohtsuki   
Nature Geoscience   8(9) 686-689   Oct 2015   [Refereed]
Saturn's F ring is a narrow ring of icy particles, located 3,400 km beyond the outer edge of the main ring system. Enigmatically, the F ring is accompanied on either side by two small satellites, Prometheus and Pandora, which are called shepherd s...
