Relating Jupiter's auroral features to magnetospheric sources

摘要: Auroral Phenomen Other Planets Geophysical Mon © 2012. American 10.1029/2011GM The magnetospheric processes responsible for Jupiter’s auroral emissions differ from those that drive the Earth’s aurora. For example, main are associated with breakdown of plasma corotation in middle magnetosphere and not, as at Earth, boundary between open closed magnetic flux. In this chapter, we review some features describe how they map to source regions or dynamic processes. Identifying polar has been difficult because global field models inaccurate beyond inner (<30 RJ). However, a recently developed model relates measured flux different radial local time locations equivalent ionosphere (rather than tracing lines model) provides more accurate way relate sources and, particularly, identify constrain size location cap. results give insight into dynamics nature Jovian magnetosphere.
