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.
Multi-mission O-C data on eRO-QPE2 reveal hierarchical super-periods consistent with apsidal precession at a~140 Rg but no robust EMRI solution due to sparse sampling and narrow likelihood peaks.

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.
