Shock acceleration as source of the anomalous component of cosmic rays in the heliosphere
(PU vir CHO, 1995)
Anomalous cosmic rays are low energy enhancements of the cosmic ray intensities that cannot be
explained by standard modulation of galactic cosmic rays entering the heliosphere. Presently it
is thought that these anomalous ...
