STUDY OF GRAVITATIONAL MIXING WITH MAGNETIC FIELD / S. I. Glazyrin, M. Yu. Eguzhova, V. P. Statsenko, Yu. V. Yanilkin, V. A. Zhmaylo // Р. 3
The problem of gravitational mixing with magnetic field for ideal MHD is studied in the paper. The boundary between two different fluids is initially plane, the magnetic field is parallel to the contact surface. The developing instability leads to the turbulent mixing zone, which mixes both density and magnetic field. As a result impacts of magnetic field on the mixing zone and the mixing zone on magnetic field are obtained. The latter is described with the proposed semi-empirical model.

A MULTIFLOW MODEL AND A NUMERICAL TECHNIQUE FOR CALCULATE INITIATION AND MOTION OF RAREFIED PLASMA IN MAGNETIC FIELD / I. M. Anisina, G. V. Dolgoleva, V. A. Zhmailo, N. V. Tarasova // Р. 11

A multiflow model for calculate initiation and motion of rarefied plasma in geomagnetic field («multiflow» MHD approximation) is described in the work. Numerical technique to calculate using this model (six-flow version) is presented. The results of calculations carried out for explosion in «Starfish» american operation are compared with the experimental data.

STATIONARY BOUND STATES OF DIRAC PARTICLES IN THE SCHWARZSCHILD GRAVITATIONAL FIELD / M. A. Vronsky, M. V. Gorbatenko, N. S. Kolesnikov, V. P. Nezna mov, E. Yu. Popov, I. I. Safronov // Р. 30
It is for the first time that undecaying stationary bound states of elementary spin 1/2 particles are validated and simulated numerically for the Schwarzschild gravitational field using a self-conjugate Hamiltonian with a scalar product for any value of the gravitational coupling constant.
In order to obtain a discrete energy spectrum, we introduce a boundary condition such that components of the vector of current density of such Dirac particles are zero near the «event horizon».
At small values of the coupling constant, the energy spectrum is close to the hydrogen-like spectrum.
Based on the results of this study, we can assume that there exists a new type of collapsars, for which the Hawking radiation mechanism is not present. From the standpoint of cosmology, if the value of the gravitational coupling constant is small, α << 1, the new type of nonradiating relict collapsars can manifest itself only through gravitation. Thus, they are good candidates for the role of «dark matter» carriers.

MAGNETIC FIELD AND β-CURRENT CALCULATIONS OF STARFISH EXPLOSION AREA / V. A. Zhmaylo, A. N. Zalyalov, N. V. Ivanov, A. A. Pushkaryov, I. V. Sobolev, A. E. Shirokov // Р. 47
Calculations of the Starfish nuclear explosion parameters realized in the frames of the Dominic operation conducted by US in 1962 are described in this paper. The calculation results for the phase of the magnetic cavern expansion are compared with experimental data obtained using magnetometers and β-radiation gauges installed on control rockets flying through the explosion cloud.
