Accretion and destruction of planetesimals in turbulent disks
Shigeru Ida, Tristan Guillot, Alessandro Morbidelli
We study the conditions for collisions between planetesimals to be accretional or disruptive in turbulent disks, through analytical arguments based on fluid dynamical simulations a…

Infall of planetesimals onto growing giant planets: onset of runaway gas accretion and metallicity of their gas envelopes
Masakazu Shiraishi, Shigeru Ida
We have investigated the planetesimal accretion rate onto giant planets that are growing through gas accretion, using numerical simulations and analytical arguments. We derived the…

Formation of Hot Planets by a combination of planet scattering, tidal circularization, and Kozai mechanism
M. Nagasawa, S. Ida, T. Bessho
We have investigated the formation of close-in extrasolar giant planets through a coupling effect of mutual scattering, Kozai mechanism, and tidal circularization, by orbital integ…
