Happy new Year 2014 from LPP

Top left:
Expansion of the solar wind - Numerical simulation of the evolution of a plasma volume advected by the solar wind between 21 and 210 solar radii: progressive formation of radial structures (red fast jets, slow jets in blue, green intermediate speeds) from an initially isotropic turbulence.

Bottom right:
Plasma speaker. These are ionization waves in air excited by a high voltage modulated at acoustic frequencies. In propagating through the air between the electrode tip and the ground plane, these ionization waves generate small shock waves. When these shock waves are generated at audible frequencies, the plasma can generate music!
