Slowing Down Type II Migration of Gas Giants to Match Observational Data
Shigeru Ida, Hidekazu Tanaka, Anders Johansen +2
The mass and semimajor axis distribution of gas giants in exoplanetary systems obtained by radial velocity surveys shows that super-jupiter-mass planets are piled up at > 1 au, whi…
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…
Radial migration of gap-opening planets in protoplanetary disks. I. The case of a single planet
Kazuhiro D. Kanagawa, Hidekazu Tanaka, Ewa Szuszkiewicz
A large planet orbiting a star in a protoplanetary disk opens a density gap along its orbit due to the strong disk-planet interaction and migrates with the gap in the disk. It is e…
Light Scattering by Fractal Dust Aggregates. II. Opacity and Asymmetry Parameter
Ryo Tazaki, Hidekazu Tanaka
Optical properties of dust aggregates are important at various astrophysical environments. To find a reliable approximation method for optical properties of dust aggregates, we cal…
