Low-frequency electromagnetic fluctuations and plasma heat conductivity

Stationary spectra of short-wave convective and magnetostatic fluctuations and the coefficient of anomalous heat conductivity are obtained in the ion-compressible plasma, βi∼1 and βe<<1. The non-zero ion pressure results in a decrease of the potential spectrum intensity and width, whereas essential nonlinear broadening due to magnetic nonlinearities is expected in a plasma with βe∼1. The electron heat conductivity is not strongly affected by non-zero ion beta. (orig.)
