Vortex-like Structure in the Cusp–Magnetosheath Interface
Two-point observations by the INTERBALL satellite pair unveiled a presence of a large vortex-like structure filled by slow and heated plasma in the outer cusp during periods of the positive BZ interplanetary magnetic field (IMF) component. We have found the rotation of the magnetic field and the decrease of its magnitude connected with the presence of a hot plasma population inside the vortex. ...
متن کاملMulti-point observations of intermittency in the cusp regions
In this paper we investigate the statistical properties of magnetic field fluctuations measured by the four Cluster spacecraft in the cusp and close to the interface with the magnetospheric lobes, magnetopause and magnetosheath. At lower altitudes along the outbound orbit of 26 February 2001, the magnetic field fluctuations recorded by all four spacecraft are random and their Probability Distri...
متن کاملCusp algebras
By a cusp V we shall mean the image of the unit disk D under a bounded injective holomorphic map h into C whose derivative vanishes at exactly one point. The simplest example is the Neil parabola, given by h(ζ) = (ζ, ζ). See [3, 4] for background and theory on the Neil parabola, which is pictured in Figure 1. A generalization of a cusp is a petal. A petal is the image of the unit disk D under a...
متن کاملMirror mode structures in the Jovian magnetosheath
[1] Mirror mode waves are commonly observed in planetary magnetosheaths. Their magnetic signatures are often periodic but occasionally appear as intermittent increases of field magnitude (peaks) or as intermittent decreases (dips). We define quantitative mirror structure identification criteria and statistically analyze the distributions of the various forms. A survey of all the relevant magnet...
متن کاملIMP 8 magnetosheath ®eld comparisons with models
This study presents cross-sectional vector maps of the magnetic ®eld derived from IMP 8 magnetometer in the magnetosheath at 30 Re behind the Earth. In addition the vector patterns of the magnetosheath ®eld for northward, southward, and east-west interplanetary magnetic ®eld (IMF) directions are qualitatively compared with those obtained from the Spreiter-Stahara gas dynamic (GD) and Fedder-Lyo...
