Temperature stabilization of intabilities in force-free magnetospheres.
Abstract
Relative streaming between particle species may arise naturally in magnetospheres to maintain a force-free charge density. Such streaming causes instabilities which are stabilized by temperature. Relativistic stability conditions are calculated, and it is shown that an energy spread of about 1.5 gammas can stabilize pulsar electron-positron plasmas for a reasonable parameter range. Compact radio sources without strong beaming may be relatively immune to temperature stabilization, however.
