Waves, Coriolis force and the dynamo effect

| Sumario: | Dynamo activity caused by waves in a rotating magnetoplasma is investigated. In astrophysical environments such as accretion disks and at sufficiently small spatial scales, the Hall effect is likely to play an important role. It is shown that a combination of the Coriolis force and Hall effect can produce a finite α-effect by generating net helicity at small scales. The shear/ion-cyclotron normal mode of the Hall plasma is the dominant contributor to the dynamo action for short-scale motions. |
