New growth mechanism of dust grains in protoplanetary disks with magnetically driven disk winds
Tetsuo Taki, Koh Kuwabara, Hiroshi Kobayashi +1
We discovered a new growth mode of dust grains to km-sized bodies in protoplanetary disks that evolve by viscous accretion and magnetically driven disk winds (MDWs). We solved an a…
Magnetohydrodynamics in a Cylindrical Shearing Box
Takeru K. Suzuki, Tetsuo Taki, Scott S. Suriano
We develop a framework for magnetohydrodynamical (MHD) simulations in a local cylindrical shearing box by extending the formulation of the Cartesian shearing box. We construct shea…
Impacts of dust feedback on a dust ring induced by a planet in a protoplanetary disk
Kazuhiro D. Kanagawa, Takayuki Muto, Satoshi Okuzumi +3
When a planet forms a deep gap in a protoplanetary disk, dust grains cannot pass through the gap. As a consequence, the density of the dust grains can increase up to the same level…
Dust and gas density evolution at a radial pressure bump in protoplanetary disks
Tetsuo Taki, Masaki Fujimoto, Shigeru Ida
We investigate the simultaneous evolution of dust and gas density profiles at a radial pressure bump located in a protoplanetary disk. If dust particles are treated as test particl…
