| Abstract: | A general theory of rotational discontinuities is developed and the changes in the components of the plasma pressure, p| and p, and in the magnetic induction, B, are found. For a given value of λ=(p| − p) 4πμ/B2 upstream only a limited range of downstream anisotropies are possible. If λ>0.6 upstream then isotropy is not possible downstream. Some special solutions are analysed and the identification of rotational discontinuities is the solar wind is discussed. |
