Morphologies of Planetary Nebulae with Close-Binary Nuclei
Published online by Cambridge University Press: 19 July 2016
Abstract
We will present photographic and CCD images of planetary nebulae that are known, on the basis of photometric observations of the central stars, to possess close-binary nuclei. All of the orbital periods range from 2.7 to 16 hours, except for the 16-day binary nucleus of NGC 2346.
