X-ray observations of Tidal Disruptions Events (TDEs) are a unique probe of the physics of accretion around supermassive black holes, as they are thought to transition from super- to sub-Eddington accretion on timescales of months/years. The first TDE candidates were found in the X-rays with the ROSAT All-Sky Survey, but, today, most of our candidates are found in the optical. While optical surveys have increased our numbers of TDE candidates enormously, it remains unclear where the optical emission originates, and if X-ray TDEs are part of the same population. Discovering TDEs in X-rays is key to understanding the emission mechanisms and rates of TDEs where the stellar debris is efficiently accreting on to the black hole. In this talk I will discuss the current state of the field, and what questions astronomers hope that eROSITA will resolve.
