Longitudinal waves in a perpendicular collisionless plasma shock: Part 3. Te ∼ Ti

This paper considers electrostatic waves in a Vlasov plasma of unmagnetized ions and magnetized electrons undergoing an E x B drift. The linear dispersion relation is solved numerically for T_e ΰT_i. For a fixed ratio of drift velocity to electron thermal velocity, the growth rates of the E x B electron drift instability are smaller, and the waves are stabilized at much smaller values of k. B than in the T_e T_i case.
