Launching of Conical Winds and Axial Jets from the Disk-Magnetosphere Boundary: Axisymmetric and 3D Simulations
M. M. Romanova, G. V. Ustyugova, A. V. Koldoba +1
We investigate the launching of outflows from the disk-magnetosphere boundary of slowly and rapidly rotating magnetized stars using axisymmetric and exploratory 3D magnetohydrodyna…
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…
