Particle-Gas Dynamics in the Midplane of a Protoplanetary Nebula

  title={Particle-Gas Dynamics in the Midplane of a Protoplanetary Nebula},
  author={Jeffrey N. Cuzzi and Anthony R. Dobrovolskis and Joelle M. Champney},
Abstract In this paper, we study the stage of planetary formation during which the particulate material is still dispersed as centimeter-to-meter sized primordial aggregates. During this stage, particles are able to settle toward the midplane into a layer of mass density comparable to or much greater than that of the gas. Nonlinear, coupled interactions between the particles and the nebula gas become significant and ultimately determine the vertical profiles of the particle density and the mean…

Particles in the nebular midplane: Collective effects and relative velocities
Abstract– In the absence of global turbulence, solid particles in the solar nebula tend to settle toward the midplane, forming a layer with enhanced solids/gas ratio. Shear relative to the
We present local two-dimensional and three-dimensional hybrid numerical simulations of particles and gas in the midplane of protoplanetary disks (PPDs) using the Athena code. The particles are
A Numerical Turbulence Model for Multiphase Flows in the Protoplanetary Nebula
It is thought that planets form from solid particles in a flattened, rotating, 99% gaseous nebula. These grains gradually coagulate into millimeter‐to‐meter sized aggregates which settle toward the
Particle-Trapping Eddies in Protoplanetary Accretion Disks
Abstract In this paper, we present a new mechanism for number density enhancement and size segregation of particles in a nonlaminar accretion disk, e.g., the solar nebula. It can be shown that, if
Kinematics of solid particles in a turbulent protoplanetary disc
We perform numerical simulations of solid particle motion in a shearing box model of a protoplanetary disc. The accretion flow is turbulent due to the action of the magnetorotational instability.
Mid‐plane sedimentation of large solid bodies in turbulent protoplanetary discs
We study the vertical settling of solid bodies in a turbulent protoplanetary disc. We consider the situation when the coupling to the gas is weak or equivalently when the particle stopping time τ st
Production and damping of turbulence by particles in the solar nebula
We have developed a “one-equation” model for the turbulent boundary layer surrounding the midplane of the solar nebula and compared it with the “zero-equation” (Prandtl) model used in our previous
Gravitational instability in the dust layer of a protoplanetary disk: Interaction of solid particles with turbulent gas in the layer
Gravitational instability of the dust layer formed after the aggregates of dust particles settle toward the midplane of a protoplanetary disk under turbulence is considered. A linearized system of


A turbulent two-phase flow model for nebula flows
A new and very efficient turbulent two-phase flow numericaly model is described to analyze the environment of a protoplanetary nebula at a stage prior to the formation of planets. Focus is on
The dynamical evolution of the protosolar nebula
Evolutionary models for protostellar nebulae are calculated under the hypothesis that the only source for the turbulent viscosity is thermal convection. The viscous stress is approximated by an
Particle-gas dynamics in the protoplanetary nebula
In the past year we made significant progress in improving our fundamental understanding of the physics of particle-gas dynamics in the protoplanetary nebula. Having brought our code to a state of
Direct numerical simulations of turbulent convection: I. Variable gravity and uniform rotation
Abstract Turbulent convection may have played a major role in determining the structure and evolution of the primordial solar nebula, but current, incomplete models of convection and turbulence give
