Two Candidate KH 15D–like Systems from the Zwicky Transient Facility

KH 15D contains a circumbinary disk that is tilted relative to the orbital plane of central binary. The precession and motion binary together produce rich phenomena in photometric light curve. In this work, we present discovery preliminary analysis two objects resemble key features from Zwicky Transient Facility. These new objects, Bernhard-1 Bernhard-2, show large-amplitude ($>1.5\,$mag), long-duration (more than tens days), periodic dimming events. A one-sided screen model developed behaviour these physical interpretation which tilted, warped occulting inner Changes object curves suggest potential periods over timescales longer 10 years. Additional spectroscopic observations are encouraged better understand nature interesting systems.
