The problem of the gas withdrawal from an Iguassu gas centrifuge (GC) at the speed of rotation, over 1000 m/s is considered. We focus our attention on the problem of achieving of optimal waste flow and friction power of the gas scoop simultaneously.

Observations of active galactic nuclei show increasing number of cases when the kinetic luminosity of jets exceeds the bolometric luminosity of disks. We develop a model of so-called cold disk accretion when the majority of the angular momentum is ca

A time-dependent numerical simulation of relativistic wind interaction with interstellar medium was performed. The winds are ejected from the magnetosphere of rotation-powered pulsars. The particle flux in the winds is isotropic while the energy flux

The toroidal magnetic field frozen in the relativistic plasma ejected by pulsars must play a significant role in the formation of jet-like features observed in the central parts of plerions. We performed a semiquantitative analysis and calculations o

We interpret the observed X-ray morphology of the central part of the Crab Nebula (torus + jets) in terms of the standard theory by Kennel and Coroniti (1984). The only new element is the inclusion of anisotropy in the energy flux from the pulsar in

We study the effect of magnetic-field axial asymmetry on the magnetocentrifugal acceleration of plasma when it flows in a source’s rotating magnetosphere (propeller effect). For an axisymmetric steady plasma flow, the first corrections to the energ

Violation of the axial synnetry of a magnetic field essentially modifies the physics of the plasma outflow in the magnetosphere of rotating objects. In comparison to the axisymmetric outflow, two new affects appear: more efficient magnetocentrifugal

The Yohkoh satellite has registered X-ray spectra of two solar flares with a linelike feature in the region 400-500 keV. Analysis shows that this feature can be interpreted as gamma-ray lines from excited 7Li and 7Be produced from α+ α reactions. T
