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…
Oscillations of MHD shock waves on the surfaces of T Tauri stars
A. V. Koldoba, G. V. Ustyugova, M. M. Romanova +1
This work treats the matter deceleration in a magnetohydrodynamics radiative shock wave at the surface of a star. The problem is relevant to classical T Tauri stars where infalling…
Modeling interaction of relativistic and nonrelativistic winds in binary system PSR 1259-63/SS2883. I.Hydrodynamical limit
S. V. Bogovalov, D. Khangulyan, A. V. Koldoba +2
In this paper, we present a detailed hydrodynamical study of the properties of the flow produced by the collision of a pulsar wind with the surrounding in a binary system. This wor…
2D and 3D MHD Simulations of Disk Accretion by Rotating Magnetized Stars: Search for Variability
M. M. Romanova, A. K. Kulkarni, M. Long +4
We performed 2D and full 3D magnetohydrodynamic simulations of disk accretion to a rotating star with an aligned or misaligned dipole magnetic field. We investigated the rotational…
