A new era for TDEs

The advent of wide-sky surveys at all wavelengths has quickly increased the number of TDEs observed and revealed a surprising over-representation of TDEs in E+A galaxies. This overrepresentation further worsens the difference between observed and theoretically predicted TDEs for non-E+A galaxies. Classical loss cone theory focuses on the cumulative effect of many weak scatterings and rarer strong scattering. However, a strong scattering can remove the star from the distribution before it could get tidally disrupted. Most stars undergoing TDEs come from within the radius of influence, the densest environments of the universe. In such peculiar environments, close encounters rare elsewhere become non-negligible. Hence, in our revised loss cone theory version we take into account classical two-body interactions as well as strong scattering, collisions, tidal captures, and study under which conditions close encounters could shield the loss cone. 

After 11 years of hibernation, another jetted TDE has been observed. In the meanwhile, there also have been observations of trans-relativistic outflows. Motivated by this wealth of possible outcomes, here we are introducing different scenarios for the jet interaction with its environment. Finally, we will also discuss polarization emission to disentangle between jetted and non-jetted TDEs.
