Effect of stellar heating on TDE and the place of TDE in Black Hole demography

 Tidal Disruption Events (TDE), or the burst of emission due to the tidal disruption of stars by Supermassive Black Holes (SMBH), are a unique laboratory to probe various high energy astrophysical phenomena much like the X-ray binaries, although in higher black hole masses. As such they might be considered as short-lived Active Galactic Nuclei (AGN). The X-ray lightcurves of TDE have been shown to depend on the structure of the star getting disrupted. In the first part of this talk, we investigate the effect of stellar heating on the X-ray emission of TDE. In particular, attributing the stellar heating to the annihilation of dark matter particles inside the star gives us a tool of investigating the effect of stellar evolution and orbits near the SMBH. We investigate the implications of the proposed stellar heating on the X-ray observations of TDE. In the second part of this talk, we try to find the place of TDE in the unification of accretion phenomena across the different black hole masses. For this, we try to compare the optical to X-ray emission from TDE with a sample of AGN of different masses and accretion rates, and from galactic black holes in the different states. This will, in turn, give us clues about the unification of TDE themselves.
