Application of the disk instability model to all quasiperiodic eruptions
X Pan, SL Li, X Cao - The Astrophysical Journal, 2023 - iopscience.iop.org
After the first quasiperiodic eruption (QPE; GSN 069) was reported in 2019, four other
sources have been identified as a QPE or a candidate. However, the physics behind QPEs …
