WebThe effect of the conductance of Jupiter’s ionosphere is considered, showing that a long auroral footprint tail is favored by high Pedersen conductance in the ionosphere. The current patterns in these cases show a U-shaped footprint due to the generation of field-aligned current on the Jupiter-facing and Jupiter-opposed sides of Io, which may ... WebAbstract. We investigate the role of the ionosphere in the development of intense, narrow discrete auroral arcs. Our study shows that interactions between a pair of downward and upward magnetic field-aligned currents (FACs) and the ionosphere can lead to the narrowing of the upward current channel and broadening of the downward current …

WebThe ionosphere is also where the auroras occur when solar wind particles collide with oxygen and nitrogen atoms. The IRI transmits at frequencies between 2.7 and 10 MHz with a power of 3.6 megawatts. It transmits radio waves upward into the ionosphere, where they cause electrons to move in waves. Web[6] In this paper we will show how the ionosphere can change the width of the discrete …
Webthe auroral zone include an additional source term in equation (6) representing effects of multiple ionizations of the ionosphere by the precipitating energetic electrons [e.g., Sato, 1978; Watanabe et al., 1993; Pokhotelov et al., 2002]. That term requires some additional assumptions about electrons acceleration in the upward current channel ...
