Late stages of the expansion of planetary nebulae.
Abstract
The authors present expansion velocities and radial space velocities of 15 very large planetary nebulae with linear radii between 0.4 and 0.8 pc, deduced from Fabry-Pérot-spectrometry. The results are discussed in terms of the interaction of the envelopes with the surrounding interstellar material during the late stages of nebular expansion.
