The Secular Periodic Evolution of X-ray Quasi-periodic Eruptions Driven by Star-disc Collisions
Jiajun Xian, Fupeng Zhang, Liming Dou +1
We study the secular periodic evolution of quasi-periodic eruptions (QPEs) for GSN069 and eRO-QPE2 assuming that they are driven by star-disc collisions. We set up numerical simula…
