Abstract: | The leading term of the electron density perturbations around a harmonic point source moving with a superthermal velocity through a maxwellian plasma is studied for distances that tend to zero. Pronounced asymmetry is found, the field being concentrated mainly in a conical region downstream behind the source (the Cherenkov cone). |
