Recent discovery of 20 TeV radiation from the Vela pulsar confirms (tentatively, at the level of crude estimates) the Aristotelian Electrodynamics picture of pulsar radiation: pulsars shine, mostly in GeV, by annihilating colliding Poynting fluxes into curvature radiation near the light cylinder. The observed GeV photons are the curvature radiation of electrons/positrons with Lorentz factors ~10^8. These "super-ultra-relativistic" electrons/positrons must also produce TeV radiation by inverse Compton if low-energy target photons are available, as they are in the Vela pulsar.

Pulsar Rockets and Gaia Neutron Star Binaries

The pulsar rocket force is exactly zero in ideal force-free electrodynamics, and Gaia neutron star eccentricities require rockets only for certain pre-supernova binary configurations.
