Probing the Bardeen-Petterson Effect in Tidal Disruption Events with Spectral line Reverberation Mapping
Original language description
In this work we investigate properties of a time-resolved fluorescent iron line originating from a warped disk that is irradiated by the initial X-ray flare. We find that the time-resolved spectrum shows distinct features before and after a critical time. This critical time depends on the BP radius rBP, i.e., the outer boundary of the inner aligned disk, while the line width during the later stage of the X-ray flare is sensitive to the inclination of the outer disk flow. This demonstrates that time-resolved X-ray spectroscopy can be a powerful tool to probe the BP effect in TDE flares and can be used to measure the BP radius as well as put constraints on the black hole mass and spin.
