Probing orbits of stellar mass objects deep in galactic nuclei with quasiperiodic eruptions

Abstract

The paper successfully models X-ray observational aspects of Quasi-Periodic Eruptions (QPEs) in galactic nuclei as due to collisions between a Tidal Disruption Event (TDE) accretion disk and a stellar mass black hole or main sequence star orbiting around a nuclear supermassive black hole (SMBH). This can have key implications in understanding EMRIs and stellar orbits in the vicinity of SMBHs.
