From Planetesimal to Planet in Turbulent Disks. II. Formation of Gas Giant Planets
Hiroshi Kobayashi, Hidekazu Tanaka
In the core accretion scenario, gas giant planets are formed form solid cores with several Earth masses via gas accretion. We investigate the formation of such cores via collisiona…
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…
Toward Understanding the Origin of Asteroid Geometries: Variety in Shapes Produced by Equal-Mass Impacts
Keisuke Sugiura, Hiroshi Kobayashi, Shu-ichiro Inutsuka
More than a half of asteroids in the main belt have irregular shapes with the ratios of the minor to major axis lengths less than 0.6. One of the mechanisms to create such shapes i…
Three-dimensional structure of clumpy outflow from supercritical accretion flow onto black holes
Hiroshi Kobayashi, Ken Ohsuga, Hiroyuki R. Takahashi +4
We perform global three-dimensional (3D) radiation-hydrodynamic (RHD) simulations of out- flow from supercritical accretion flow around a 10 Msun black hole. We only solve the outf…
