The effects of a magnetic field on planetary migration in laminar and turbulent discs
M. L. Comins, M. M. Romanova, A. V. Koldoba +2
We investigate the migration of low-mass planets ( and ) in accretion discs threaded with a magnetic field using 2D MHD code in polar coordinates. We o…
Numerical MHD Codes for Modeling Astrophysical Flows
A. V. Koldoba, G. V. Ustyugova, P. S. Lii +4
We describe a Godunov-type magnetohydrodynamic (MHD) code based on the Miyoshi and Kusano (2005) solver which can be used to solve various astrophysical hydrodynamic and MHD proble…
The effect of an ordered azimuthal magnetic field on a migrating planet in a non-turbulent disc
M. L. Comins, M. M. Romanova, A. V. Koldoba +2
In this work, we consider the physics of the interaction between a planet and a magnetized gaseous protoplanetary disc. We investigate the migration of a planet in a disc that is t…
Advection of Matter and B-Fields in Alpha-Discs
S. Dyda, R. V. E. Lovelace, G. V. Ustyugova +3
We have carried out and analyzed a set of axisymmetric MHD simulations of the evolution of a turbulent/diffusive accretion disc around an initially unmagnetized star. The disc is i…
Disk-Magnetosphere Interaction and Outflows: Conical Winds and Axial Jets
M. M. Romanova, G. V. Ustyugova, A. V. Koldoba +1
We investigate outflows from the disk-magnetosphere boundary of rotating magnetized stars in cases where the magnetic field of a star is bunched into an X-type configuration using…
Hydrodynamics of interaction of pulsar and stellar winds and its impact on the high energy radiation of binary pulsar systems
D. V. Khangulyan, F. A. Aharonian, S. V. Bogovalov +2
The hydrodynamics of the interaction of pulsar and stellar winds in binary systems harboring a pulsar and its impact on the nonthermal radiation of the binary pulsar PSR B1259-63/S…
