ZTF J0139+5245

Below are the available photometric data for ZTF J0139+5245 from the Zwicky Transient Facility (ZTF) through DR17 and from ongoing Las Cumbres Observatory (LCO) 1.0-meter observations. ZTF J0139+5245 is a white dwarf that was discovered to exhibit irregularly-shaped transit events caused by broken-up planetary material that recur on a roughly 104-day period (Vanderbosch et al. 2020).

A newly discovered system exihibiting dips similar those seen in ZTF J0139+5245, but recurring on a slightly longer timescale of about 180-190 days. Currently investigating the nature of this object, but providing the ZTF DR17 and ongoing LCO observations here for those interested in monitorig the dip events.
