Special Friday Seminar:
New Insights into the Solar-Wind Termination

Observations from the Voyager spacecraft, near the solar-wind termination shock and in the inner heliosheath, have confirmed many previous ideas, but have also raised new questions and generated significant controversy.
The observations mandate a blunt termination shock that was moving rapidly inward at the time of the Voyager 1 shock crossing. The effects of these properties of the shock on the energetic particles are significant.
I will address new effects of the bluntness and shock motions, in the framework of the picture of particle acceleration at the termination shock. These show encouraging agreement with observations.
