Searching for Boyajian's Star Analogs with the Zwicky Transient Facility

We present results from a systematic search of the Zwicky Transient Facility (ZTF) survey for Boyajian's Star analogs. This unique F star exhibits repeated, infrequent short-term variability ("dips") and a long-term gradual decrease in brightness. The physical origin of variability in this otherwise unremarkable star is not understood, and it is the sole known example. Kepler observed over 150,000 stars and found a single Boyajian's Star. Over 200 million well-sampled light curves comprise the ZTF catalog, making it a rich dataset to search for similar stars. We apply a metric to search ZTF light curves for Boyajian-like dips, discuss their known properties, and propose follow-up observations for the most promising candidates.
