The authors examine the effect of finite electron temperatures on the growth rate of proton mirror instabilities. They find that if the electron temperature is comparable with the parallel proton temperature that the mirror instability growth rate is slowed by the presence of a parallel electric field. This field is generated as a result of pressure gradients in the electron distribution. These finite electron temperature effects are seen to have little impact on the thresholds for the instability, but to impact the growth rate, compressibility, and polarization much more strongly.
