Abstract

A new model is presented for the radio emission from hot stars. Electrons are accelerated to relativistic energies by shocks in the wind near the star and emit radio radiation through the synchrotron mechanism. The particle energy spectrum and radio spectrum for this model are derived; the model can account for many of the observed characteristics of some recently discovered stars which have peculiar radio emission. These particles may make hot stars significant sources of gamma-rays, cosmic rays, or both.
