Mirror structures above and below the linear instability threshold : Cluster observations, fluid model and hybrid simulations
Using 5 years of Cluster data, we present a detailed statistical analysis of magnetic fluctuations associated with mirror structures in the magnetosheath. We especially focus on the shape of these fluctuations which, in addition to quasi-sinusoidal forms, also display deep holes and high peaks. The occurrence frequency and the most probable location of the 5 various types of structures is discu...
متن کاملMagnetic holes in plasmas close to the mirror instability
Non-propagating magnetic hole solutions in anisotropic plasmas near the mirror instability threshold are investigated in numerical simulations of a fluid model that incorporates linear Landau damping and finite Larmor radius corrections calculated in the gyrokinetic approximation. This FLR-Landau fluid model reproduces the subcritical mirror bifurcation recently identified on the Vlasov-Maxwell...
متن کاملCluster magnetic field observations in the magnetosheath: four-point measurements of mirror structures
The Cluster spacecraft have returned the first simultaneous four-point measurements of the magnetosheath. We present an analysis of data recorded on 10 November 2000, when the four spacecrafts observed an interval of strong mirror-like activity. Correlation analysis between spacecraft pairs is used to examine the scale size of the mirror structures in three dimensions. Two examples are presente...

15 صفحه اولSuperradiance and Instability of Black Holes
We discuss the relation between the superradiance phenomenon and the instability of rotating black holes in higher dimensions. In particular, we point out that the superradiant instability of a massless scalar field around a simply rotating KerradS black hole implies the gravitational instability of that black hole for tensor-type perturbations. ∗) E-mail: [email protected] 1 typeset using PT...
