Influence of the Interstellar Medium on the Shaping of Planetary Nebulae

Abstract
The interaction of the ISM with the evolution of PNe is studied for cases where there is a large relative velocity between ISM and central star, for example for high-proper motion PNe. In such cases the ISM wind already interacts strongly with the AGB wind, and extensive PN asymmetries result.
