A Cyclic Burst Rate Behavior of a Persistent X-ray Burster: Recent XMM-Newton and NuSTAR Observations of 4U 1323-62
Tugba Boztepe, Tolga Guver, Ersin Gogus +4
In this study, we report partly simultaneous XMM-Newton and NuSTAR observations of the bursting, dipping low mass X-ray binary, 4U 1323-62 obtained in 2024. 4U 1323-62 is one of th…
The 2020 Superburst of 4U 1608-522 and its impact on the accretion disk
Tugba Boztepe, Tolga Guver, Elif Ece Devecioglu +9
Superbursts are rare events observed from bursting neutron star low mass X-ray binaries. They are thought to originate from unstable burning of the thick layer of Carbon on the sur…
Thermal Spectra of Warped and Broken Accretion Disks
J. Speicher, O. Blaes
Black holes may accrete gas with angular momentum vectors misaligned with the black hole spin axis. The resulting accretion disks are subject to Lense-Thirring precession, and henc…
Examining the Relationship Between the Persistent Emission and the Accretion Rate During a Type I X-ray Burst
J. Speicher, D. R. Ballantyne, P. C. Fragile
The accretion flow onto a neutron star will be impacted due to irradiation by a Type I X-ray burst. The burst radiation exerts Poynting-Robertson (PR) drag on the accretion disk, l…
