Effect of the acceleration current on the centrifugal interchange instability
[1] The centrifugal interchange instability is the primary driver of radial plasma transport in the magnetospheres of Jupiter and Saturn. Most previous theoretical treatments of this instability have ignored the role of the acceleration current and have assumed that the divergence of the centrifugal drift current in the magnetosphere is closed by Pedersen currents in the underlying ionosphere, ...
متن کاملCompressibility effect on magnetic-shear-localized ideal magnetohydrodynamic interchange instability
Sangeeta Gupta, J. D. Callen and C. C. Hegna Department of Engineering Physics, University of Wisconsin, Madison, WI 53706-1687 (Dated: July 8, 2004) Abstract Eigenmode analysis of a magnetic-shear-localized ideal magnetohydrodynamic (MHD) interchange instability in the presence of plasma compressibility indicates the marginal stability criterion (DI = 1/4) is not affected by the compressibilit...
متن کاملInfluence of the Coriolis force on the instability of slowly pulsating B stars
This paper explores the effect of rotation on the κ-mechanism instability of slowly pulsating B stars. A new nonadiabatic code, that adopts the so-called ‘traditional approximation’ to treat the Coriolis force, is used to investigate the influence exerted by rotation over the stability of stellar models covering the mass range 2.5M⊙ 6 M∗ 6 13.0M⊙. The principal finding is that, for all modes co...
متن کاملUnderstanding inertial instability on the f-plane with complete Coriolis force
We present analytical results allowing to understand the influence of usually neglected vertical component of the Coriolis force and of the vertical velocity contribution in its horizontal component upon wave-trapping in shear flows in stratified fluid, and upon related inertial instability.
متن کاملRule Interchange on the Web
Rules play an increasingly important role in a variety of Semantic Web applications as well as in traditional IT systems. As a universal medium for publishing information, the Web is envisioned to become the place for publishing, distributing, and exchanging rule-based knowledge. Realizing the importance and the promise of this vision, the W3C has created the Rule Interchange Format Working Gro...
