| Abstract: |
The jets seen in NGC 6543 motivated us to search for similar features in other PNe. We used our HST snapshot program to look for jets using the [N II] and Hα narrow-band filters. Although spectacular jets are found in proto-PNe, true jets seem rare among mature PNe. In the latter group, IC 4593 is the best case in our sample. We distinguish between jets and a number of interesting "jet-like" features, e.g., "cometary" structures with a dense globule at the end facing the central star. |
