The Secular Periodic Evolution of X-Ray Quasiperiodic Eruptions Driven by Star−Disk Collisions
Publié 2025-01-01Accéder au texte intégralWe study the secular periodic evolution of quasiperiodic eruptions (QPEs) for GSN069 and eRO-QPE2 assuming that they are driven by star−disk collisions. We set up numerical simulations and compared them with the observed periodic decay of ∼−3160 ± 720 s yr ^−1 in GSN069 and ∼−370 ± 40 s yr ^−1 in eR...

A Torus Remnant Revealed by the Infrared Echo of Tidal Disruption Event AT 2019qiz: Implications for the Missing Energy and Quasiperiodic Eruption Formation
Publié 2025-01-01Accéder au texte intégralAT 2019qiz is the first standard optical tidal disruption event (TDE) with detection of X-ray quasiperiodic eruptions (QPEs), providing strong evidence for TDE–QPE association. Moreover, it belongs to the rare subset of optical TDEs with prominent infrared (IR) echoes revealed by the multiepoch phot...
