New Close Binary Central Stars of Planetary Nebulae from Gaia DR3 Epoch Photometry
arXiv:2209.00352 · doi:10.3847/2515-5172/ac8e6c
Abstract
Close binary interactions perform a key role in the formation and shaping of planetary nebulae. However only a small fraction of Galactic planetary nebulae are known to host close binary systems. Many such systems are detectable through photometric variability. We searched recently published epoch photometry data from Gaia DR3 for planetary nebula central stars with periodic photometric variability indicative of binarity, uncovering four previously unknown close binaries.
