The first stellar tidal disruption flare in ZTF: from photometric selection to multi-wavelength characterization

Leads: Sjoert van Velzen (UMd)

Objects: ZTF18aabtxvd (aka ZTF-NedStark, AT2018zr)

Observations: ZTF light curve, Swift UVOT photometry, XMM X-ray imaging, VLA radio imaging

Brief Description: We report the independent discovery of the transient source AT2018zr during commission observations of the Zwicky Transient Facility (ZTF), the first tidal disruption event (TDE) found in this survey. The ZTF light curve of the TDE samples the rise-to-peak exceptionally well, with 50 days of g and r-band detections before the time of maximum light. We also present our multi-wavelength followup observations that were triggered by the discovery of this flare: the detection of a weak X-ray source and a stringent upper limit to the radio emission.
