A new perspective concerning the influence of the solar wind on the Jovian magnetosphere

摘要: The solar wind exerts a strong influence on the Jovian magnetosphere in changing its volume, energizing plasma, and stimulating aurora host of other associated effects. However, whereas at Earth dominant terrestrial coupling process is magnetic reconnection, energy reservoir Jupiter's magnetospheric continually present, kinetic rotating plasma disk. This “flywheel”’ produces effects with no analogy, some which we describe here. most surprising prediction from analysis this paper that remotely sensed symptoms activity are likely to occur conjunction pressure decreases. Compressions produced by forward shocks increases will heat but substantially reduce ionosphere-magnetosphere current systems. intensity dayside radio wave emissions increased ionospheric-magnetospheric systems tend anticorrelate compressions correlate expansions. link based an argument auroral zone maps disk middle thus linked sheet dynamics. effect expansion increase parallel pressure, setting up conditions can produce detached “blobs” enhance mass loss. particularly apposite light opportunities for observing wind-Jovian interactions using data both Galileo Cassini spacecraft during flyby Jupiter late 2000, ideally supplemented imaging ground-based Hubble telescopes.
