Tidal disruption event associated with the quasi-periodic eruptions from GSN 069: Possible disruption of a common envelope.

WANG D.

Abstract (from CDS):

Context. X-ray quasi-periodic eruptions (QPEs) from the galactic nucleus have been found in several galaxies. Among them, GSN 069 is the only one with a tidal disruption event (TDE), which was recently found to have brightened again 9 years after the main outburst.
Aims. However, the origin of this TDE is still unclear. This Letter explores a particular model for the TDE.
Methods. By comparing the fallback time with observations, we found the TDE could not be caused by the disruption of the envelope of a single star in the tidal stripping model. Thus, we suggest that it is a disruption of a common envelope (CE).
Results. By calculating the fallback rate of such a model, we reproduced the second peak in the observed TDE light curve. If this model is correct, this TDE will be the closest observation to a direct observation of CE, which has never been directly observed.
