- W4313892705 abstract "The ROSAT-selected tidal disruption event (TDE) candidate RX J133157.6-324319.7 (J1331), was detected in 1993 as a bright (0.2-2 keV flux of $(1.0 pm 0.1) times 10^{-12}$ erg s$^{-1}$ cm$^{-2}$), ultra-soft ($kT=0.11 pm 0.03$ keV) X-ray flare from a quiescent galaxy ($z=0.05189$). During its fifth All-Sky survey (eRASS5) in 2022, SRG/eROSITA detected the repeated flaring of J1331, where it had rebrightened to an observed 0.2-2 keV flux of $(6.0 pm 0.7) times 10^{-13}$ erg s$^{-1}$ cm$^{-2}$, with spectral properties ($kT=0.115 pm 0.007$ keV) consistent with the ROSAT-observed flare $sim$30 years earlier. In this work, we report on X-ray, UV, optical, and radio observations of this system. During a pointed XMM observation $sim$17 days after the eRASS5 detection, J1331 was not detected in the 0.2-2 keV band, constraining the 0.2-2 keV flux to have decayed by a factor of $gtrsim$40 over this period. Given the extremely low probability ($sim5times 10^{-6}$) of observing two independent full TDEs from the same galaxy over a 30 year period, we consider the variability seen in J1331 to be likely caused by two partial TDEs involving a star on an elliptical orbit around a black hole. J1331-like flares show faster rise and decay timescales ($mathcal{O}(mathrm{days})$) compared to standard TDE candidates, with neglible ongoing accretion at late times post-disruption between outbursts." @default.
