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…
Numerical simulations of coronal magnetic field loop evolution
T. G. Yelenina, G. V. Ustyugova, A. V. Koldoba
We present the results of the numerical simulations of the interaction between a magnetized star and an imperfectly conducting accretion disk. To analyze the ''star-disk'' interact…
"Propeller" Regime of Disk Accretion to Rapidly Rotating Stars
G. V. Ustyugova, A. V. Koldoba, M. M. Romanova +1
We present results of axisymmetic magnetohydrodynamic simulations of the interaction of a rapidly-rotating, magnetized star with an accretion disk. The disk is considered to have a…
Propeller-driven Outflows and Disk Oscillations
M. M. Romanova, G. V. Ustyugova, A. V. Koldoba +1
We report the discovery of propeller-driven outflows in axisymmetric magnetohydrodynamic simulations of disk accretion to rapidly rotating magnetized stars. Matter outflows in a wi…
