SELF-SIMILAR SOLUTIONS FOR THE ACCELERATION OF COSMIC RAYS AT A SUPERNOVA SHOCK PROPAGATING INTO A CIRCUMSTELLAR WIND

摘要

Cosmic ray acceleration may occur at a supernova shock expanding into a circumstellar wind. Self-similar solutions for the cosmic ray distribution are derived firstly when diffusion is isotropic and secondly when the wind sustains a magnetic field in the form of a Parker spiral.
