Abstract
- Close binarity can play a significant role in the shaping of planetary nebulae (PNe) as the system evolves through the common-envelope phase. We present the detection of two of the shortest orbital periods among PN binary central stars. These are Hen 2-428, a bipolar PN, and V458 Vul, a recent nova surrounded by a mildly bipolar planetary nebula. The properties of the central stars of these systems, of their nebulae and their possible fate are discussed.<br />Comment: 6 pages, 2 figures, to appear in the proceedings of the Asymmetric Planetary Nebulae V conference
