- Space plasmas;
In situ observation showed that efficient particle acceleration occurs in the region around comets. Emphasis has been given on the second-order Fermi acceleration process, by which cometary ions can be efficiently accelerated provided that the hydromagnetic turbulence around comets consists of waves of different phase velocities. In the light of accumulated information on the cometary environment, we shall re-evaluate several acceleration models.
