| Zusammenfassung |
| Excitation of Weibel magnetic fields in an initially non-magnetized though
anisotropic plasma may trigger other low-frequency instabilities fed by
pressure anisotropy. It is shown that under Weibel-like stable conditions the
Weibel-like thermal fluctuation magnetic field allows for restricted
Firehose-mode growth. In addition, low-frequency Whistlers can also propagate
in the plasma under certain anisotropic conditions. When the Weibel-like mode
becomes unstable, Firehose instability ceases but Mirror modes take over.
This will cause bubble structures in the Weibel-like field in addition to
filamentation. |
