NICER observation list: Target ID 764606

Abstract

The canonical picture of Tidal Disruption Events (TDEs) suggests that the soft X-ray emission should rise sharply then decline smoothly over months, but in recent years, NICER and Swift high-cadence monitoring has revealed that the X-rays frequently do not follow this simple prescription. Furthering our understanding requires more complete late-time coverage to search for rebrightening, measure spectral evolution, and characterize any short-term variability. Based on a systematic X-ray archival analysis, we have identified 6 targets well suited for late-time follow-up. We propose to obtain NICER late-time follow-up of these TDEs, in order to test how they compare to evolution predicted by models of viewing-angle unification and slim disk evolution.
