PRODUCTION OF ANOMALOUS COSMIC-RAYS FROM PICK-UP IONS AND THEIR INWARD DIFFUSION FROM THE TERMINATION SHOCK OF THE SOLAR-WIND

An investigation of the upwind-downwind asymmetries in the heliospheri c pressure distributions of the anomalous cosmic my species is present ed. The time-independent hydrodynamic cosmic ray diffusion equation is solved analytically starting from precalculated element-specific sour ce distributions of the high energy particles at the solar wind termin ation shock which serves as their source surface. The source distribut ions are derived from the strongly asymmetric pick-up ion fluxes which arrive at the termination shock and represent the seed population for the anomalous components. The resulting upwind-downwind asymmetries o f the cosmic ray pressure distributions in the heliosphere are calcula ted assuming that the source surface is spherically symmetric with a n early linear dependence of the source strength on the local pick-up io n fluxes.
