Rossby Wave Instability in Astrophysical Discs
R. V. E. Lovelace, M. M. Romanova
A brief review is given of the Rossby wave instability (RWI) in astrophysical discs. In non-self-gravitating discs, around for example a newly forming stars, the instability can be…
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…
The effect of an ordered azimuthal magnetic field on a migrating planet in a non-turbulent disc
M. L. Comins, M. M. Romanova, A. V. Koldoba +2
In this work, we consider the physics of the interaction between a planet and a magnetized gaseous protoplanetary disc. We investigate the migration of a planet in a disc that is t…
Magnetospheric Accretions and the Inner Winds of Classical T Tauri Stars
Ryuichi Kurosawa, M. M. Romanova
Recent spectropolarimetric observations suggest that young low-mass stars such as classical T Tauri stars (CTTSs) possess relatively strong (~kG) magnetic field. This supports a sc…
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…
