Accretion and plasma outflow from dissipationless discs
Sergei Bogovalov, Stanislav Kelner
We consider an extreme case of disc accretion onto a gravitating centre when the viscosity in the disc is negligible. The angular momentum and the rotational energy of the accreted…
MHD models and synthetic synchrotron maps for the jet of M87
J. Gracia, S. Bogovalov, K. Tsinganos
We present a self-consistent MHD model for the jet of M87. The model consist of two distinct zones: an inner relativistic outflow, which we identify with the observed jet, and an o…
Magnetically Collimated Jets with High Mass Flux
S. Bogovalov, K. Tsinganos
Recent numerical simulations and analytical models of magnetically collimated plasma outflows from a uniformly rotating central gravitating object and/or a Keplerian accretion disk…
Magnetic collimation of the solar and stellar winds
K. Tsinganos, S. Bogovalov
We resolve the paradox that although magnetic collimation of an isotropic solar wind results in an enhancement of its proton flux along the polar directions, several observations i…
On the magnetic acceleration and collimation of astrophysical outflows
S. Bogovalov, K. Tsinganos
The axisymmetric 3-D MHD outflow of a cold plasma from a magnetized and rotating astrophysical object is numerically simulated with the purpose of investigating the outflow's magne…
