AB: Efforts to understand the dawn-dusk asymmetries of the Jovian magnetosphere lead to new ways of thinking about the process of reconnection in the magnetotail. Outflowing plasma, accelerated by the centrifugal stresses on the rotating flux tube, strongly depletes the inner portion of the flux tube, which can then readily reconnect. The reconnection produces a zone of depleted closed flux tubes at the outer boundary of the plasma disk. The irreversible outflow and associated loss of heavy ions maintains a quasi-steady state in the Jovian magnetosphere.
