Abstract The scattering of galactic cosmic rays by the fluctuations in the magnetic field embedded in the solar wind transfers energy and momentum to the cosmic-ray gas. The hydrodynamic equations of the wind, including both these effects, are integrated. The nature of the solutions depends critically on the model chosen for the variation of the diffusion coefficient K with heliocentric distance. It is found that, in order to obtain solutions which give reasonable values for the cosmic-ray pressure at infinity, the diffusion coefficient must vary with heliocentric distance in such a way that, at distances greater than ~-~-`4 au., K increases to a value very much larger than its value at I au. With such models of K(r) the cosmic-ray gas then exerts only a small influence on the wind Publication: The Astrophysical Journal Pub Date: November 1969 DOI: 10.1086/150237 Bibcode: 1969ApJ...158..781S full text sources ADS | Related Materials (1) Erratum: 1970ApJ...159.1133S
