Anisotropy of high-energy cosmic rays

The anisotropy of high-energy (∼10 GeV and above) cosmic rays is investigated. A simplified model of the heliosphere constructed as a basis for the theory of their long-period variations is investigated for applicability to describing the cosmic-ray anisotropy. This model has been found to need a modification. The necessary changes of the model do not affect the conclusions on the 22-year variations reached on its basis but make it possible to construct a theory of cosmic-ray anisotropy. The theoretical results on the anisotropy are compared with its long-term observations in a wide energy range performed in Yakutsk.
