3D Simulations of Planet Trapping at Disc-Cavity Boundaries
M. M. Romanova, P. S. Lii, A. V. Koldoba +4
Inward migration of low-mass planets and embryos of giant planets can be stopped at the disc-cavity boundaries due to co-orbital corotation torque. We performed the first global th…
Rossby Vortices in Thin Magnetized Accretion Discs
Loren Matilsky, Sergei Dyda, Richard V. E. Lovelace +1
We study the Rossby wave instability (RWI) in a thin accretion disc threaded by an initially toroidal magnetic field using the magnetohydrodynamics (MHD) code PLUTO. We find that f…
Numerical MHD Codes for Modeling Astrophysical Flows
A. V. Koldoba, G. V. Ustyugova, P. S. Lii +4
We describe a Godunov-type magnetohydrodynamic (MHD) code based on the Miyoshi and Kusano (2005) solver which can be used to solve various astrophysical hydrodynamic and MHD proble…
Asymmetric MHD Outflows/Jets from Accreting T Tauri Stars
Sergei Dyda, Richard V. E. Lovelace, Galina V. Ustyugova +3
Observations of jets from young stellar objects reveal the asymmetric outflows from some sources. A large set of D MHD simulations has been carried out for axisymmetric viscou…
MHD Simulations of Magnetospheric Accretion, Ejection and Plasma-field Interaction
M. M. Romanova, R. V. E. Lovelace, M. Bachetti +5
We review recent axisymmetric and three-dimensional (3D) magnetohydrodynamic (MHD) numerical simulations of magnetospheric accretion, plasma-field interaction and outflows from the…
Magnetically Driven and Collimated Jets from the Disc-Magnetosphere Boundary of Rotating Stars
R. V. E. Lovelace, M. M. Romanova, P. Lii
We discuss recent progress in understanding the launching of outflows/jets from the disc-magnetosphere boundary of slowly and rapidly rotating magnetized stars. In most of the disc…
Propeller outflows from an MRI disc
Patrick S Lii, Marina M. Romanova, Galina V. Ustyugova +2
We present the results of axisymmetric simulations of MRI-driven accretion onto a rapidly rotating, magnetized star accreting in the propeller regime. The stellar magnetosphere cor…
Advection of Matter and B-Fields in Alpha-Discs
S. Dyda, R. V. E. Lovelace, G. V. Ustyugova +3
We have carried out and analyzed a set of axisymmetric MHD simulations of the evolution of a turbulent/diffusive accretion disc around an initially unmagnetized star. The disc is i…
Magnetic launching and collimation of jets from the disk-magnetosphere boundary: 2.5D MHD simulations
Patrick S Lii, Marina M. Romanova, Richard V. Lovelace
We use axisymmetric magnetohydrodynamic (MHD) simulations to investigate the launching and collimation of jets emerging from the disk-magnetosphere boundary of accreting magnetized…
