Binary Central Stars Of Planetary Nebulae Discovered Through Photometric Variability. Iii. The Central Star Of Abell 65, Todd Hillwig, David J. Frew, Melissa Louie, Orsola De Marco, Sam Schaub

Todd Hillwig

A growing number of close binary stars are being discovered among central stars of planetary nebulae. Recent and ongoing surveys are finding new systems and contributing to our knowledge of the evolution of close binary systems. The push to find more systems was largely based on early discoveries which suggested that 10%–15% of all central stars are close binaries. One goal of this series of papers is confirmation and classification of these systems as close binaries and determination of binary system parameters. Here we provide time-resolved multi-wavelength photometry of the central star of Abell 65 as well as further analysis …
