Expansion of a plasma cloud into the solar wind
  Three-dimensional (3D) hybrid particle-in-cell (PIC) simulations, with kinetic ions and fluid electrons, of a plasma cloud expansion in the solar wind are presented, revealing the dynamics of the expansion, with shock formation, magnetic field compression, and the solar wind ions deflection around the plasma bubble. The similarities of this system with a magnetosphere are also pointed out.
