Can stellar-mass black hole growth disrupt disks of active galactic nuclei? The role of mechanical feedback
Hiromichi Tagawa, Shigeo S. Kimura, Zoltán Haiman +3
Stellar-mass BHs (sBHs) are predicted to be embedded in active galactic nuclei (AGN) disks due to gravitational drag and in-situ star formation. However, we find that due to a high…
Eccentric gap induced by a super-Jupiter mass planet
Yuki A. Tanaka, Kazuhiro D. Kanagawa, Hidekazu Tanaka +1
A giant planet embedded in a protoplanetary disk opens a gap by tidal interaction, and properties of the gap strongly depend on the planetary mass and disk parameters. Many numeric…
Rapid formation of Gas Giant Planets via Collisional Coagulation from Dust Grains to Planetary Cores
Hiroshi Kobayashi, Hidekazu Tanaka
Gas-giant planets, such as Jupiter, Saturn and massive exoplanets, were formed via the gas accretion onto the solid cores each with a mass of roughly ten Earth masses. However, rap…
Dust rings as a footprint of planet formation in a protoplanetary disk
Kazuhiro D. Kanagawa, Takayuki Muto, Hidekazu Tanaka
Relatively large dust grains (referred to as pebbles) accumulate at the outer edge of the gap induced by a planet in a protoplanetary disk, and a ring structure with a high dust-to…
Collisional Growth and Fragmentation of Dust Aggregates with Low Mass Ratios. I: Critical Collision Velocity for Water Ice
Yukihiko Hasegawa, Takeru K. Suzuki, Hidekazu Tanaka +2
We investigated fundamental processes of collisional sticking and fragmentation of dust aggregates by carrying out N-body simulations of submicron-sized icy dust monomers. We exami…
