Alive but barely kicking: News from 3+yr of Swift and XMM-Newton X-ray monitoring of quasiperiodic eruptions from eRO-QPE1
Original language description
In this study, we present results from strategically designed Swift observing programs spanning the past 3 yr, aimed at tracking eruptions from eRO-QPE1. Our main results are as follows: (1) the recurrence time of eruptions can vary from flare to flare and is in the range of 0.6-1.2 days, (2) there is no detectable secular trend in evolution of the recurrence times, (3) consistent with prior studies, their eruption profiles can have complex shapes, and (4) the peak flux of the eruptions has been declining over the past 3 yr, with the eruptions barely detected in the most recent Swift data set taken in 2023 June. This trend of weakening eruptions has been reported recently in GSN 069. However, because the background luminosity of eRO-QPE1 is below our detection limit, we cannot verify whether the weakening is correlated with the background luminosity (as is claimed to be the case for GSN 069). We discuss these findings within the context of various proposed QPE models.
