Sommario

Si esaminano gli effetti di una rotazione uniforme sulla propagazione di piccole perturbazioni in un plasma anisotropo privo di urti. Tali effetti si manifestano in vario modo sui noti fenomeni di instabilità “hose”, “mirror” e magnetogravitazionale del tipo di Jeans. Nella prima parte si considerano perturbazioni piane, nella seconda di tipo cilindrico. Alcune considerazioni sulla stabilità e sulle onde idromagnetiche in un plasma anisotropo privo di urti sono svolte in Appendice.

Summary

The effects of a uniform rotation on the propagation of small perturbations through an anisotropic collisionless plasma are investigated. These effects are present in various ways on the well-known “hose”, “mirror” and gravitational instabilities. In Part I we consider plane perturbations, in Part II cylindrical. Some remarks about stability and hydromagnetic waves in an anisotropic collisionless plasma are given in Appendix.
