WebIt is shown that charged particles can be accelerated to high energies in astrophysical shock fronts. Fast particles are prevented from streaming away upstream of a shock front by scattering off Alfven waves which they themselves generate. This scattering confines the particles to the region around the shock and results in first-order Fermi acceleration due … WebThis web site is an online database of interplanetary shocks observed by the Wind and ACE spacecraft.

WebThe possibility of cosmic ray acceleration by shock waves has been considered by many workers during the last twenty years on the basis of various assumptions on the exact nature of the acceleration mechanism. The paper examines the question further on the assumption that the cosmic rays are constrained to move diffusively with respect to the background … WebThe acceleration to relativistic energies of the high-energy tail of the particle distribution produced by a shock front is discussed. In order to be accelerated, particles need be able to pass through the shock without being strongly deflected. It is argued, using earth's bow shock as an example, that a shock front produces large numbers of protons, and …
