AMRI as a dissipation-induced instability of the Chandrasekhar equipartition solution

In winter 1956 S. Chandrasekhar wrote: “One nice result which nevertheless came out at this time was the proof of the stability of the equipartition solution. Wentzel and Goldberger checked my analysis as I could not quite believe the result myself.”

(“A scientific autobiography: S. Chandrasekhar”, K. C. Wali, ed. , World Scientific, Singapore, 2010, p. 38)

Our recent article demonstrates destabilization of the Chandrasekhar equipartition solution of ideal MHD even by an infinitesimally weak dissipation:
