Advection/Diffusion of Large-Scale B-Field in Accretion Disks
R. V. E. Lovelace, D. M. Rothstein, G. S. Bisnovatyi-Kogan
Activity of the nuclei of galaxies and stellar mass systems involving disk accretion to black holes is thought to be due to (1) a small-scale turbulent magnetic field in the disk (…
Stability of the Magnetopause of Disk-Accreting Rotating Stars
R. V. E. Lovelace, L. Turner, M. M. Romanova
We discuss three modes of oscillation of accretion disks around rotating magnetized neutron stars which may explain the separations of the kilo-Hertz quasi periodic oscillations (Q…
Launching of Poynting Jets from Accretion Disks
R. V. E. Lovelace, M. M. Romanova
The jets observed to emanate from many compact accreting objects may arise from the twisting of the magnetic field threading a differentially rotating accretion disk which acts to…
Launching of Jets by Propeller Mechanism
M. M. Romanova, R. V. E. Lovelace, G. V. Ustyugova +1
We carried out axisymmetric simulations of disk accretion to a rapidly rotating magnetized star in the "propeller" regime. Simulations show that propellers may be "weak" (with no o…
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…
Conical Winds from the Disk-Magnetosphere Boundary
M. M. Romanova, G. V. Ustyugova, A. V. Koldoba +1
A new type of wind - a conical wind - has been discovered in axisymmetric magnetohydrodynamic simulations of the disk-magnetosphere interaction in cases where the magnetic field of…
