چکیده
Giant planets embedded in protoplanetary disks (PPDs) can create annulus density gaps around their orbits the type-II regime, potentially responsible for ubiquity of annular substructures observed PPDs. Despite substantial amount works studying planet migration and gap properties, they are almost exclusively conducted under viscous accretion disk framework. However, recent studies have established magnetized winds as primary driving evolution, which co-exist with turbulence from magneto-rotational instability (MRI) outer We conduct a series 3D global non-ideal magneto-hydrodynamic (MHD) simulations planet-disk interaction applicable to Our properly resolve MRI accommodate MHD wind. found that triggers poloidal magnetic flux concentration its orbit.

Global three-dimensional simulations of magnetic field evolution in a galactic disk II. Gas rich galaxies
A fully three-dimensional computation of induction processes in a disk is performed to investigate the evolution of a large-scale magnetic field in gas-rich barred and spiral galaxies in the presence of field diffusion. As input parameters we use time dependent velocity fields obtained from selfconsistent 3D N-body calculations of galactic dynamics. Our present work primarily analyzes the influ...
متن کاملGlobal three-dimensional simulations of magnetic field evolution in a galactic disk I. Barred galaxies
The evolution of three-dimensional, large-scale, magnetic fields, in a galactic disk is investigated numerically. The N-body simulations of galactic dynamics are incorporated into the kinematic calculations of induction equations to study the influence of non-axisymmetric gas flows on the galactic magnetic field. The time-dependent gas velocity fields are introduced as input parameters for the ...
متن کاملThree-dimensional fluid simulations of a simple magnetized toroidal plasma
Three-dimensional fluid simulations are performed in a simple magnetized toroidal plasma, in which vertical and toroidal magnetic fields create helicoidal magnetic field lines that terminate on the torus vessel. The simulations are carried out in the three-dimensional flux tube that wraps around the torus and are able to describe both interchange and drift-wave dynamics. The presence of differe...
متن کاملRayleigh-Taylor-Unstable Accretion and Variability of Magnetized Stars: Global Three-Dimensional Simulations
We present results of 3D simulations of MHD instabilities at the accretion diskmagnetosphere boundary. The instability is Rayleigh-Taylor, and develops for a fairly broad range of accretion rates and stellar rotation rates and magnetic fields. It produces tall, thin tongues of plasma that penetrate the magnetosphere in the equatorial plane. The shape and number of the tongues changes with time ...
