Forming pressure-traps at the snow-line to isolate isotopic reservoirs in the absence of a planet
Sébastien Charnoz, Guillaume Avice, Ryuki Hyodo +2
Pressure maxima are regions in protoplanetary disks where pebbles can be trapped because of the local absence of pressure gradient. These regions could be ideal places to form plan…
Tidal pull of the Earth strips the proto-Moon of its volatiles
S. Charnoz, P. A. Sossi, Y-N Lee +7
Prevailing models for the formation of the Moon invoke a giant impact between a planetary embryo and the proto-Earth \citep{Canup_2004, Cuk_Stewart_2012}. Despite similarities in t…
SPH Simulations for Shape Deformation of Rubble-Pile Asteroids Through Spinup: The Challenge for Making Top-Shaped Asteroids Ryugu and Bennu
Keisuke Sugiura, Hiroshi Kobayashi, Sei-ichiro Watanabe +3
Asteroid Ryugu and asteroid Bennu, which were recently visited by spacecraft Hayabusa2 and OSIRIS-REx, respectively, are spinning top-shaped rubble piles. Other axisymmetric top-sh…
Erosion and accretion by cratering impacts on rocky and icy bodies
Ryuki Hyodo, Hidenori Genda
During planet formation, numerous small impacting bodies result in cratering impacts on large target bodies. A fraction of the target surface is eroded, while a fraction of the imp…
A "no-drift" runaway pile-up of pebbles in protoplanetary disks in which midplane turbulence increases with radius
Ryuki Hyodo, Shigeru Ida, Tristan Guillot
A notable challenge of planet formation is to find a path to directly form planetesimals from small particles. We aim to understand how drifting pebbles pile up in a protoplanetary…
Planetesimal formation around the snow line. II. Dust or pebbles?
Ryuki Hyodo, Tristan Guillot, Shigeru Ida +2
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…
