ABSTRACT
This chapter aims to study resistive magnetohydrodynamic (MHD) modes modified by drift effects, that is, resistive drift–MHD modes. It explains the allowance method for drift effects in the general problem of resistive MHD modes. The chapter argues that drifts effects lead to a decrease in the growth rate of the resistive-interchange instability but do not stabilize it. For strong drift effects the real part of the frequency of this instability proves small compared with the growth rate. The chapter shows that the growth rates of both the reconnecting mode and the internal resistive m = 1 kink mode decrease for strong drift effects. In this case the real part of the frequency of the reconnecting mode is equal to the electron drift frequency, while that of the internal resistive kink mode is small compared with the growth rate. The chapter considers the effect of the electron thermal conductivity on resistive drift–MHD modes.
