Inductive interaction of electroconductive bodies with ionospheric and interplanetary plasma

The hypersonic hyperalfvèn plasma flow around electroconductive bodies is considered and electromagnetic inductive plasma-body interaction is analyzed. The possible applications of results obtained in this analysis to body motion in ionosphere and interplanetary plasma are discussed.     

Non-linear behaviour effect on Mach cone behind the body moving in rarefied ionosphere

The problem of rarefied plasma flow near the body in highly rarefied ionized planet atmosphere is considered. Plasma is supposed to be non-isothermal, T_i ? T_e. In the case of thermodynamically non-equilibrium electrons the solution of modified Korteweg-de Vries equation is estimated in the Mach cone region behind the body and it is shown that Mach cone appears to be curved.
