CosmicRay Flow Lines and Energy Changes
Abstract
In this paper we discuss the particle flow or streaming and energy changes of cosmic rays in the interplanetary region via flow lines in momentumposition space. We consider the steadystate case where particles are released monoenergetically from the Sun or from infinity and study the cosmicray ‘traffic pattern’ in momentum and position arising from monoenergetic sources. The analysis makes extensive use of the resultleft< {dot p} rightrangle = tfrac{1}{3}pV {text{ }}G (wherep is the particle momentum,V the solar wind velocity andG the cosmicray density gradient) for the mean time rate of change of momentum of cosmic rays reckoned for a fixed volume in a reference frame fixed in the solar system, developed by us in several recent papers.
