Ion acoustic soliton propagation in a magnetized relativistic plasma

  • Published:
Il Nuovo Cimento D

Summary

The Korteweg-de Vries equation for ion acoustic waves in the presence of weakly relativistic ion streaming velocity is derived in a magnetic plasma. It is found that relativistic effects are important in the solitary wave propagation for both fast and slow modes. Earlier results are reconfirmed.

Riassunto

Si deduce in un plasma magnetico l’equazione di Kortewg-de Vries per le onde acustiche di ioni in presenza di una velocità di filtramento degli ioni debolmente relativistica. Si trova che gli effetti relativistici sono importanti nella propagazione d’onda solitaria sia per i modi veloci sia per quelli lenti. Si riconfermano i risultati precedenti.

Резюме

В намагниченной плазме выводится уравнение Кортевега де Фриза для ионных акустических волн в присутствии слабо релятивистского ионного потока. Получается, что релятивистские эффекты являются важными при распространении уединенных волн для быстрых и медленных мод. В работе подтверждаются ранее полученные результаты.
