SPH simulations of zero-energy partial TDEs find fallback ~t^{-9/4}, optical luminosities 10^{42-44} erg/s at 10^4 K and radii 10-100 au, indicating many detected TDEs may be partial rather than full.

A time-dependent model shows that star-disk collisions in TDE systems hosting EMRIs can eject 10^{-3} to 1 solar masses at 0.02-0.1c years after the initial flare, producing radio emission via interaction with circumnuclear material.
Larger black holes in TDEs accrete more material and launch faster winds, with unbound mildly relativistic winds for higher viscosity parameters and bound convective outflows for lower ones.
3D hydro simulations show that TDE outflow interactions with a broken power-law CNM can reproduce the range of observed radio light curves via early flares inside the Bondi radius and possible late rebrightenings outside it.
The paper provides observing strategies, detection forecasts, and predictions for using SKA and VLBI to study radio emission from tidal disruption events around supermassive black holes.

Are most detected tidal disruption events partial?

Delayed Radio Flares in Tidal Disruption Events from Star-Disk Collision Outflows
A time-dependent model shows that star-disk collisions in TDE systems hosting EMRIs can eject 10^{-3} to 1 solar masses at 0.02-0.1c years after the initial flare, producing radio emission via interaction with circumnuclear material.

Simulations of interaction between outflow and surrounding broken power-law circumnuclear medium: implications for different radio light curves of TDEs
3D hydro simulations show that TDE outflow interactions with a broken power-law CNM can reproduce the range of observed radio light curves via early flares inside the Bondi radius and possible late rebrightenings outside it.
