Three dimensional energetic ion bulk flows in the mass-loaded region of Comet P/Giacobini-Zinner
Abstract
Three dimensional ion bulk flows in the mass loaded region around comet P/Giacobini-Zinner are investigated using energetic ion data from the EPAS experiment on the ICE spacecraft. Relatively abrupt changes in flow speed of ~ 100-km s-1 are found at the bow wave crossings. Within the bow wave, the flow is deflected away from the comet tail axis by up to 30°. Ions with energies of ~ 300-keV are found in this region, suggesting that other ion acceleration processes occur in addition to solar wind pickup.
