N-BODY SIMULATION OF PLANETESIMAL FORMATION THROUGH GRAVITATIONAL INSTABILITY OF A DUST LAYER IN LAMINAR GAS DISK
We investigate the formation process of planetesimals from the dust layer by the gravitational instability in the gas disk using local N-body simulations. The gas is modeled as a background laminarExpand
The Possibility of the Kelvin–Helmholtz Instability during Sedimentation of Dust Grains in the Protoplanetary Disk
We reexamine the possibility of shear-driven turbulence during the sedimentation of dust grains in the protoplanetary disk. Shear-driven turbulence is expected to occur before the onset of aExpand
N-Body Simulation of Planetesimal Formation through Gravitational Instability of a Dust Layer
We performed N-body simulations of a dust layer without a gas component and examined the formation process of planetesimals. We found that the formation process of planetesimals can be divided intoExpand
N-body Simulation of Planetesimal Formation Through Gravitational Instability and Coagulation. II. Accretion Model
The gravitational instability of a dust layer is one of the scenarios for planetesimal formation. If the density of a dust layer becomes sufficiently high as a result of the sedimentation of dustExpand
INDUCED TURBULENCE AND THE DENSITY STRUCTURE OF THE DUST LAYER IN A PROTOPLANETARY DISK
We study the turbulence induced in the dust layer of a protoplanetary disk based on the energetics of dust accretion due to gas drag. We estimate turbulence strength from the energy supplied by dustExpand
Effect of dust on Kelvin-Helmholtz instabilities
Context. Dust is present in a large variety of astrophysical fluids, ranging from tori around supermassive black holes to molecular clouds, protoplanetary discs, and cometary outflows. In many suchExpand
SECULAR GRAVITATIONAL INSTABILITY OF A DUST LAYER IN SHEAR TURBULENCE
We perform a linear stability analysis of a dust layer in a turbulent gas disk. Youdin investigated the secular gravitational instability (GI) of a dust layer using hydrodynamic equations with aExpand
Onset of the Kelvin-Helmholtz instability in partially ionized magnetic flux tubes
Context. Recent observations of solar prominences show the presence of turbulent flows that may be caused by Kelvin-Helmholtz instabilites (KHI). However, the observed flow velocities are below theExpand
Planetesimal Formation by Gravitational Instability of a Porous-Dust Disk
Recently it is proposed that porous icy dust aggregates are formed by pairwise accretion of dust aggregates beyond the snowline. We calculate the equilibrium random velocity of porous dust aggregatesExpand
Kelvin–Helmholtz instabilities in multi-sized dust layers
We examine the effect of the dust size distribution on Kelvin-Helmholtz instabilities in the protoplanetary disk with dust sedimentation. With newly taking into account the dust size distribution,Expand
