And under the resultant acceleration substantial dawn-dusk asymmetries in the energetic particle flows are produced. In addition, ion cyclotron effects were shown to have impor-tant consequences on the convection of different ion species within the magnetosphere and that even he++ and o6+ would undergo mass separation effects and not necessarily.

The dawn/dusk asymmetries are particularly intriguing, killen says. While sodium is a volatile element, calcium is not easily vaporized. Magnesium can be found in both volatile and refractory minerals.
Dawn-dusk asymmetries are ubiquitous features of the plasma environment of many of the planets in our solar system. They occur when a particular process or feature is more pronounced at one side of a planet than the other. For example, recent observations indicate that earth's magnetopause is thicker at dawn than at dusk.

Auroral particle precipitation exhibits dawn‐dusk asymmetries that reflect the asymmetries in the particle populations, waves, and processes in the magnetosphere. The diffuse auroral electrons can be observed mainly in 22:00–09:00 mlt, which coincides with much of the spatial distribution of the whistler‐mode chorus waves that have been shown to be the predominant mechanism for pitch.

Nificant, persistent dawn–dusk asymmetries throughout the solar-wind–magnetosphere–ionosphere system.

Statistical observations by the themis spacecraft show a dawn-dusk asymmetry in plasma parameters within the earth's magnetosheath. Proton density and temperature are greater on the dawnside while.
It is well known that solar wind imposes local time asymmetries on the structure of a planetary magnetosphere. However, less appreciated are the asymmetries associated with current distributions, particle fluxes and auroral intensities whose origin though not fully understood is thought to originate in the plasma dynamics driven by the solar wind.
It is shown that asymmetry between dawn and dusk at mercury is controlled by the finite gyroradius of ions and by convection electric fields.
Dawn-dusk asymmetries in kelvin–helmholtz development at planetary boundary layers may result from several effects including plasma corotation, kinetic effects, magnetic geometry, or asymmetric distribution of plasma.

Studies of earthward plasma and magnetic field transport in the earth’s magnetotail plasma sheet have shown that, on the average, earthward ion flows in the premidnight and midnight sectors exhibit.
Magnetic field and plasma exists, especially in the properties of escaping planetary o+ ions. The asymmetry is associated with ion finite gyroradius effects. Furthermore, the imf x-component results in a dawn-dusk asymmetry. Overall, the qnh model is found to reproduce the main observed.

Such dawn-dusk asymmetries are ubiquitous features of the plasma environment of many of the planets in our solar system. Properties or processes where one would expect axial symmetry, are in reality asymmetric. Some of these asymmetries are constant and predictable and related to the orbital motion and rotation of the planet.
The dawn-dusk asymmetries in the ion outflow are sometimes non-negligible for the outflow processes and plasma circulation in geospace. The causes of the asymmetries are diverse in terms of the morphologies, efficiencies, and responses to the solar-wind conditions.

Nevertheless, local time, particularly dawn-dusk, asymmetries are observed throughout the jovian magnetosphere. For instance, the configuration of the magnetic field, the plasma flows around the planet, the current distribution, and the current sheet thickness all exhibit discrepancies between dawn and dusk.
