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…
