Mercury’s sodium exosphere: Magnetospheric ion recycling
[1] A three-dimensional Monte Carlo model of Mercury’s neutral sodium exosphere was used to describe correlation between the observed variations in the exospheric density and the variations in the surface concentration of sodium along Mercury’s motion around the Sun [Leblanc and Johnson, 2003]. Four processes of ejection were taken into account: thermal and photon stimulated desorptions, solar ...
متن کاملMagnetospheric influence on the Moon’s exosphere
[1] Atoms in the thin lunar exosphere are liberated from the Moon’s regolith by some combination of sunlight, plasma, and meteorite impact. We have observed exospheric sodium, a useful tracer species, on five nights of full Moon in order to test the effect of shielding the lunar surface from the solar wind plasma by the Earth’s magnetosphere. These observations, conducted under the dark sky con...
متن کاملMercury exosphere: I. Global circulation model of its sodium component
Our understanding of Mercury’s sodium exosphere has improved considerably in the last 5 years thanks to new observations (Schleicher, H., Wiedemann, G., Wöhl, H., Berkefeld, T., Soltau, D. [2004]. Astron. Astrophys. 425, 1119–1124) and to the publication of a summary of the large set of ground based observations (Potter, A.E., Killen, R.M., Morgan, T.H. [2007]. Icarus 186, 571–580; Potter, A.E....
متن کاملMagnetospheric ion sputtering and water ice grain size at Europa
We present the first calculation of Europa’s sputtering (ion erosion) rate as a function of position on Europa’s surface. We find a global sputtering rate of 2 10 H2O s , some of which leaves the surface in the form of O2 and H2. The calculated O2 production rate is 1 10 O2 s , H2 production is twice that value. The total sputtering rate (including all species) peaks at the trailing hemisphere ...

Owing to almost unmatched volumetric energy density, Li-ion batteries have dominated the portable electronics industry and solid state electrochemical literature for the past 20 years. Not only will that continue, but they ar...
