论文摘要
紧密的二元相互作用在行星星云的形成和塑造中起关键作用。然而,只有一小部分的银河行星星云才能容纳近距离二元系统。许多这样的系统可通过光度变异性检测到。我们搜索了Gaia DR3最近发布的Epoch光度计数据,该数据具有周期性的光度变异性,指示了二进制的周期性光度变异性,发现了四个以前未知的近距离二进制文件。
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.
