Flux stationnaires et supersoniques de protons, paralleles au champ magnétique

Abstract

Using the gyration radius as the parameter to expand the differential equation for the moments, the transport equations for highly supersonic flux, which is parallel to the magnetic field, are obtained. The maximum order one can hope to obtain for the invariants is discussed together with the relation between the function of distribution f1 proposed by Whang and that which must result at 1 AU if f1 or a bimaxwellian function are used at the origin. Using f01 at the base (~ 55 Rs) it can be estimated that the total loss of heat flux under 1 AU is of the order of 70% on condition that the values obtained after f1 are utilized.
