3D MHD Simulations of Disk Accretion onto Magnetized Stars: Numerical Approach and Sample Simulations
Marina M. Romanova, Alexander V. Koldoba, Galina V. Ustyugova +3
We present results of global 3D MHD simulations of disk accretion to a rotating star with dipole and more complex magnetic fields using a Godunov-type code based on the "cubed sphe…
Modeling of Disk-Star Interaction: Different Regimes of Accretion and Variability
Marina M. Romanova, Akshay K. Kulkarni, Min Long +1
The appearance and time variability of accreting millisecond X-ray pulsars (hereafter AMXPs, e.g. Wijnands & van der Klis 1998) depends strongly on the accretion rate, the effectiv…
Three-dimensional Simulations of Accretion to Stars with Complex Magnetic Fields
M. Long, M. M. Romanova, R. V. E. Lovelace
Disk accretion to rotating stars with complex magnetic fields is investigated using full three-dimensional magnetohydrodynamic (MHD) simulations. The studied magnetic configuration…
Accretion to Stars with Non-dipole Magnetic Fields
M. Long, M. M. Romanova, R. V. E. Lovelace
Disc accretion to a rotating star with a non-dipole magnetic field is investigated for the first time in full three-dimensional (3D) magnetohydrodynamic (MHD) simulations. We inves…
Locking of the Rotation of Disk-Accreting Magnetized Stars
M. Long, M. M. Romanova, R. V. E Lovelace
We investigate the rotational equilibrium state of a disk accreting magnetized stars using axisymmetric magnetohydrodynamic (MHD) simulations. In this ``locked'' state, the spin-up…
