Abstract Pulsar emission models often invoke wave instabilities in counterstreaming pair plasma as a mechanism to impose source coherence. The viability of the two-stream instability mechanism in a hot pair plasma, such as the one created by high-energy photons in a neutron star's magnetic field, is addressed in this paper. A two-stream dispersion relation is solved numerically, using a relativistic and covariant expression of the plasma dispersion function for a relativistic Maxwellian distribution. In the context of standard pulsar magnetospheric models, instability is demonstrated over the regions of P and P-dot parameter space in which most pulsars are found.
