Application of the Disk Instability Model to All Quasiperiodic Eruptions

Abstract After the first quasiperiodic eruption (QPE; GSN 069) was reported in 2019, four other sources have been identified as a QPE or candidate. However, physics behind QPEs is still unclear, although several models proposed. Pan et al. proposed an instability model for accretion disk with magnetically driven outflows of 069, which able to reproduce both light curve and evolution spectra fairly well. In this work, we extend all QPEs. We improve calculations spectrum by introducing hardening factor, caused deviation opacity from blackbody. find that curves candidates can be well reproduced our calculations.
