| Zusammenfassung |
| We present Prognoz-8 observations of
low-frequency plasma waves (2-105 Hz) associated with plasma fluxes near the
outer boundary of the plasma sheet. These plasma fluxes were different from the
regular plasma sheet boundary layer and consisted of tailward flowing warm
proton and cold oxygen beams accompanied by rather cold electrons (Te
less than 100 eV). Observed plasma characteristics were used in the numerical
solution of the dispersion relation for the ion-beam acoustic instability.
Detailed analysis shows that this instability can be a source of observed
emissions at frequencies up to 25 Hz. |
