3D MHD Simulations of Accretion onto Stars with Tilted Magnetic and Rotational Axes
M. M. Romanova, A. V. Koldoba, G. V. Ustyugova +3
We present results of global three-dimensional (3D) magnetohydrodynamic (MHD) simulations of accretion onto magnetized stars where both the magnetic and rotational axes of the star…
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…
Comparisons of MHD Propeller Model with Observations of Cataclysmic Variable AE Aqr
A. A. Blinova, M. M. Romanova, G. V. Ustyugova +2
We have developed a numerical MHD model of the propeller candidate star AE Aqr using axisymmetric magneto-hydrodynamic (MHD) simulations. We suggest that AE Aqr is an intermediate…
Properties of Strong and Weak Propellers from MHD Simulations
Marina M. Romanova, Alisa A. Blinova, Galina V. Ustyugova +2
We investigate the properties of magnetized stars in the propeller regime using axisymmetric numerical simulations. We modelled the propeller regime for stars with realistically la…
The effects of a magnetic field on planetary migration in laminar and turbulent discs
M. L. Comins, M. M. Romanova, A. V. Koldoba +2
We investigate the migration of low-mass planets ( and ) in accretion discs threaded with a magnetic field using 2D MHD code in polar coordinates. We o…
Boundary between Stable and Unstable Regimes of Accretion. Ordered and Chaotic Unstable Regimes
A. A. Blinova, M. M. Romanova, R. V. E. Lovelace
We present a study of the Rayleigh-Taylor unstable regime of accretion onto rotating magnetized stars in a set of high grid resolution three-dimensional (3D) magnetohydrodynamic (M…
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…
Oscillations of the Boundary Layer and High-frequency QPOs
A. A. Blinova, M. Bachetti, M. M. Romanova
We observed persistent high-frequency oscillations of the boundary layer near an accreting, weakly-magnetized star in global 3D MHD simulations. The tilted dipole magnetic field is…
Boundary Between Stable and Unstable Regimes of Accretion
A. A. Blinova, R. V. E. Lovelace, M. M. Romanova
We investigated the boundary between stable and unstable regimes of accretion and its dependence on different parameters. Simulations were performed using a "cubed sphere" code wit…
